Solve the formula for triangle

Question

Solve the formula for the indicated variable. Then
evaluate the rewritten formula for the given values. Use 3.14 for Π.

Area: A = (1/2)bh  

 

Solve for b. Find the value of b

 

When A=160 and h=20

Answer 1

Given the formula Area (A ) = (1/2)bh

Solve for b:-

A = (1/2)bh

Multiply each side by 2

2A = bh

Divide each side by h

2A /h = bh /h

2A /h = b

b = 2A /h

The value of b:-

When A = 160 and h = 20

Substitute the value of A and h in b = 2A /h

b = 2(160) /20

b = 320 / 20

b = 16 miters
