The area of a triangle is 15 / 16 square meters, the length of its bottom is 1 / 4 meters, and how many meters is its height
15/16×2÷1/4
=15/8×4
=15 / 2m
Solution: set the height as X meters
1/4×x÷2=15/16
1/8x=15/16
x=15/16÷1/8
x=15/2

Shangguan Xiaoying,
The radius is: 12.56 △ 3.14 = 4 (m)
Area: 3.14 × 4 & # 178; △ 2 = 25.12 (M2)
Granny Li fenced a square chicken fence against the wall. The fence has a total length of 24 meters and covers an area
Hello
Square side length = 24 △ 3 = 8 (m)
Floor area = 8 × 8 = 64 (M2)
Granny Li raised two chicken rolls with a fence, which are similar to a square. The first fence is 36 meters long, and the chicken roll covers an area of 10 square meters
The first roll is 36 square in circumference,
The side length should be 9
The area should be 9 * 9 = 81
Granny Li keeps a group of chickens in her yard. With the help of a wall, she uses a 12.56m long fence to encircle a semicircle chicken pen. What is the floor area of the chicken pen?
According to the meaning of the question: the circumference of a semicircle is 12.56m, because 1 / 2 π d = 12.56m, the solution is: the diameter of the chicken pen d = 8m, so the area of the chicken pen = 1 / 2 (π (D / 2)) = 1 / 2 * π * (8 / 2) = 25.12m A: the area of the chicken pen is 25.12m
