Question

The area of a triangle is given by the formula A=1/2bh, where A = the area of the triangle, b = the length of the base, and h = the height of the triangle. Solve the formula for h.

Determine the height of a triangle with an area of 45 cm2 and a base that is 9 cm long.

Answer 1

The heigh of the triangle is 10cm

Explanation:

The area of a triangle is given by the formula A=1/2bh where

A = the area of the triangle,

b = the length of the base, and

h = the height of the triangle.

To find the height when

the

Area of the triangle, A =45cm2,

base of the triangle, = 9 cm long.

Using the formula, A = 1/2 × b × h

45 = 1/2 × 9 × h

Cross multiplying

2×45 = 1×9×h

90 = 9h

h = 90/9 = 10cm
