There is a trapezoid. If the upper bottom is increased by 2 meters, the lower bottom and height will not change. Its area will increase by 4.8 square meters. If the upper bottom and the lower bottom are both unchanged, and the height is increased by 2 meters, its area will increase by 8.5 square meters. Find the area of the original trapezoid

There is a trapezoid. If the upper bottom is increased by 2 meters, the lower bottom and height will not change. Its area will increase by 4.8 square meters. If the upper bottom and the lower bottom are both unchanged, and the height is increased by 2 meters, its area will increase by 8.5 square meters. Find the area of the original trapezoid

Height of trapezoid: 2 × 4.8 △ 2 = 4.8 (m) sum of top and bottom of trapezoid: 2 × 8.5 △ 2 = 8.5 (m) area of original trapezoid: 4.8 × 8.5 △ 2 = 20.4 (M2) answer: area of original trapezoid is 20.4 square meters

The area of a trapezoid is 48 square meters, its upper bottom is 4 meters, its height is 8 meters, and its lower bottom is?

8 meters

A triangle and a parallelogram have the same base and height. It is known that the area of the parallelogram is 28 square centimeters
It would be better to be able to explain it

Because the area of a parallelogram with equal base and height is twice that of a triangle,
S parallelogram = a * h s triangle = 1 / 2A * h
28 △ 2 = 14 square centimeter

A triangle and a parallelogram have the same base and height. The area of a triangle is 25 square centimeters less than that of a parallelogram. The area of a parallelogram is ()

Because a triangle and a parallelogram have the same base and height,
So the area of a triangle is half that of a parallelogram,
The area of a triangle is 25 square centimeters, and that of a parallelogram is 50 square centimeters

The area of a parallelogram is 15 square centimeters larger than that of a triangle with the same height as its bottom. What is the area of this triangle? What is the area of a parallelogram
Answer the right person in two minutes,

The relationship between the area of a parallelogram and its triangle with the same base and equal height is that the area of a parallelogram is equal to twice the area of its triangle with the same base and equal height
Because the area of a parallelogram is 15 square centimeters larger than that of a triangle with the same height as its bottom, that is, 2S △ - s △ = 15
S△=15
The area of the triangle is 15; the area of the parallelogram is 30

(2009 · Tong'an District) a parallelogram and a triangle have the same base and height. It is known that the area of the parallelogram is 30 square centimeter, then the area of the triangle is () square centimeter
A. 45B. 30C. 15d. Not sure

30 △ 2 = 15 (square centimeter), answer: the area of triangle is 15 square centimeter, so choose: C

A triangle and a parallelogram have the same area and the same base. The height of the parallelogram is 5.6CM. What is the height of the triangle?
Please list the formula

11.2 cm

A triangle and a parallelogram have the same area and the same base. If the triangle is 9 cm, how high is the parallelogram?

18 cm

The two right sides of a right triangle are 6cm and 8cm respectively. The area of this triangle______ Square centimeter

A: the area of this triangle is 24 square centimeters. So the answer is: 24

In a semicircle with a diameter of 10 cm, draw a triangle with the largest area. How many square centimeters is the area of this triangle

The diameter is the largest at the bottom, the height is the largest at the radius, and the area is 1 / 2 * 10 * 5 = 25 square centimeter
