The formula for the area of a triangle is A = bh/2 .
Solve the formula for height. h =
A triangle has a base of 7cm and an area of 28 sq cm. What is its height?
Solve the formula for height. h =
A triangle has a base of 7cm and an area of 28 sq cm. What is its height?
To solve the formula for height, we can rearrange it as follows:
A = bh/2
Multiply both sides of the equation by 2:
2A = bh
Divide both sides of the equation by b:
h = 2A/b
Given that the base (b) is 7 cm and the area (A) is 28 sq cm, we can substitute these values into the equation to find the height (h):
h = 2(28)/7
h = 56/7
h = 8 cm
Therefore, the height of the triangle is 8 cm.
A = bh/2
Multiply both sides of the equation by 2:
2A = bh
Divide both sides of the equation by b:
h = 2A/b
Given that the base (b) is 7 cm and the area (A) is 28 sq cm, we can substitute these values into the equation to find the height (h):
h = 2(28)/7
h = 56/7
h = 8 cm
Therefore, the height of the triangle is 8 cm.
