A triangle has an area of 40 square meters, a height of 10 meters and a bottom of () meters
Eight
A square has an area of 100 square meters. What's the circumference
S=a²
=100
∵a＞0
A = 10 m
∵C=4a
∴C=4*10
=40 m
A: the circumference is 40m
The area of a triangle and a parallelogram are 100 square meters, and the bottom is 25 meters. The ratio of the height of the triangle to the height of the parallelogram is ()
The area of a triangle and a parallelogram are 100 square meters, and the bottom is 25 meters. The ratio of the height of the triangle to the height of the parallelogram is (2:1)
The height of a triangle is
100 × 2 △ 25 = 8 (m)
The height of a parallelogram is
100 △ 25 = 4 (m)
So, the high ratio is
8：4=2：1
The area of a triangle is 100m2. If the bottom edge remains unchanged, its height is increased to 10 times of the original, and its area is______ m2．
The area of a triangle is 100m2. If the bottom edge remains unchanged, increase its height to 10 times of the original,
Its area is 100 × 10 = 1000 square meters
A: its area is 1000 square meters;
So the answer is: 1000
The area of a triangle is 18 square meters, its height is 9 meters, and its corresponding bottom is______ Rice
18×2÷9，
=36÷9，
=4 (m),
A: the corresponding bottom is 4 meters,
So the answer is: 4
A triangle has an area of 2.56 square meters, a height of 2.5 meters and a bottom of several meters
2.56 * 2 / 2.5 = 2.048M
A triangular piece of land with an area of 48 square meters. Its height is 8 meters. How many meters is its bottom? (solved by equation)
If the base is x m, then
8x÷2=48
4x=48
x=12．
A: the bottom is 12 meters
The area of the triangle is 4 / 5 square meters, the height is 7 / 10 meters, and how many meters is the bottom?
2 × (4 / 5) × (7 / 10) = 16 / 7 (m)
A: the bottom is 16 / 7 meters
Bottom × height △ 2 = area
2 × area / height = bottom
The area of a triangle is 4 / 5 square meters, the height is 7 / 10 meters, and how many meters is the bottom
2 × (4 / 5) × (7 / 10) = 16 / 7 (m)
A: the bottom is 16 / 7 meters
Bottom × height △ 2 = area
2 × area / height = bottom
The area of a triangle is four fifths of a square meter. Its base is known to be 12 meters of five. What is its height
Area of triangle = 1 / 2 * base * height
Height = 2 area / bottom
=2*（4/5）/（12/5）
=8/5*（5/12）
=2 / 3M
