Answer:

b = 8 in

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here A = 12 and h = 3 , then

[tex]\frac{1}{2}[/tex] b × 3 = 12 , that is

1.5b = 12 ( divide both sides by 1.5 )

b = 8
Base is 8 inches

Area = 12 inches

Triangle area= (base • height) divided by 2
12= ( 8 • 3 ) divided by 2
