The sum of three sides of a right triangle is 48 cm, and the ratio of the three sides is 5:4:3. What is the area of this triangle?
The length of a right angle side of a triangle is:
48×3
3 + 4 + 5 = 12 (CM);
The length of the other right angle side of the triangle is:
48×4
3 + 4 + 5 = 16 (CM);
The area of the triangle is:
12×16×1
2 = 96 (bisection cm);
A: the area of this right triangle is 96 square centimeters
-The area of the parallelograms is 12 square centimeters, and the area of the triangle with its equal base and height is______ Square centimeter
12 △ 2 = 6 (square centimeter);
A: the area of the triangle is 6 square centimeters
So the answer is: 6
If the square area of a triangle is equal to the square of a parallelogram, the area of the triangle is equal to 12 cm
A triangle and a parallelogram are equal in base and height. If the area of the triangle is 12 square centimeters, the area of the parallelogram is (24) square centimeters; if the area of the parallelogram is 12 square centimeters, the area of the triangle is (6) square centimeters
The area of a triangle is 12 square centimeters, and the area of a parallelogram whose base is equal to its base is () square centimeters. If the base of a parallelogram is 4 The area of a triangle is 12 square centimeters, and the area of a parallelogram of the same base and height is () square centimeters. If the base of a parallelogram is 4cm, the height is () cm
Because a parallelogram with the same base and equal height is twice as large as a triangle
The area of parallelogram with height of 24 / 4 = 6 = base times height
A parallelogram and a triangle have the same base and height. Their area difference is 12 square decimeters. The sum of their areas is______ Square decimeter
12÷（2-1）×（2+1）
=12÷1×3
=36 (square decimeter)
A: the sum of their area is 36 square decimeters
So the answer is: 36
The area of a triangle is 16 square centimeters, and the area of a parallelogram equal to its base and height is______ .
16 × 2 = 32 (square centimeter),
Answer: the area of parallelogram with its equal base and height is 32 square centimeters;
So the answer is: 32 square centimeter
A parallelogram and a triangle are equal in base and height. The area of a triangle is known to be 20 square centimeters, and the area of a parallelogram is () square centimeters
When the base is equal to the height,
∵ triangle area = bottom × height ∵ 2
The triangle area = 1 / 2 of the parallelogram area
The area of parallelogram is 2 × 20 = 40 square centimeter
The area of a triangle is 20 square centimeters, and the area of a parallelogram equal to its base and height is
40 square centimeter
A triangle and a parallelogram have the same base and height. What percentage of the area of the triangle is the area of the parallelogram?
Area formula of parallelogram:
The area of a parallelogram is equal to the base multiplied by the height of the base
The area of the triangle is half of the base multiplied by the height of the base
So the answer is 50%
A triangle and a parallelogram are equal in height and area. If the base of the parallelogram is 2.6 cm, the base of the triangle is () cm
Five point two
