Question

what is the area of this figure? 19 ft 5 ft 7 ft 3 ft 12 ft square feet

Explanation:

Step1: Calculate the area of the first rectangle

The first rectangle has a length of \(7\) ft and a width of \(5\) ft.
The area formula for a rectangle is \(A = length\times width\).
So, \(A_1=7\times5 = 35\) square feet.

Step2: Calculate the area of the second rectangle

The second rectangle has a length of \(3\) ft and a width of \(8 - 5=3\) ft.
Using the area formula \(A = length\times width\), \(A_2 = 3\times3=9\) square feet.

Step3: Calculate the area of the third rectangle

The third rectangle has a length of \(12\) ft and a width of \(8\) ft.
Using the area formula \(A = length\times width\), \(A_3=12\times8 = 96\) square feet.

Step4: Sum up the areas of all three rectangles

\(A=A_1 + A_2+A_3\)
\(A=35 + 9+96\)
\(A = 140\) square feet.

Answer:

\(140\)
