Question

A. Write a formula for the area A

of a triangle.
b. Solve the formula for b.
c. Use the new formula to find the
base of the triangle.
A = 36 mm2
h = 6 mm
b

Answer 1

A = 1/2 b * h

b = 2A / h

b = 12

Explanation:

Remark

The formula starts out as

A = 1/2 * b * h

You want to rearrange it to show b by itself.

Formula

Multiply by 2

2A = b * h

Divide by h

2A/h = b

Part C

b = 2A / h

A = 36 mm^2

h = 6 mm

b = 2*36 / 6

b = 72 / 6

b = 12 mm
