Answer:

A =  84 inches^2

Step-by-step explanation:

We know that the formula for the area of a triangle is given by

A = 1/2 b*h

Let's substitute what we know

We need the units to be the same

Convert 7 ft to inches

1 ft = 12 inches

Multiply both sides by 7

7 ft = 84 inches

A = 1/2 *84*2

A =  84 inches^2



Heyyy0909
Area = base • height • 1/2

7ft = 84 in

84 • 2 = 168

168 • 1/2 (/2) = 84

Area is 84 sq in or 7 sq ft
