Question

find the area of this irregular shape. a = ? ft²

Explanation:

Step1: Find the height of rectangle 2

The height of rectangle 2 is \(6 - 1=5\) ft.

Step2: Find the area of rectangle 2

The width of rectangle 2 is 4 ft. Using the area formula \(A = l\times w\), the area of rectangle 2 is \(4\times5 = 20\) \(ft^{2}\).

Step3: Find the height of the third rectangle

The height of the third rectangle is \(4\) ft.

Step4: Find the total area of the irregular shape

The total area \(A=24 + 20+4\times4\).
First, calculate \(4\times4 = 16\).
Then, \(A=24+20 + 16\).
\(24+20=44\), and \(44+16 = 60\).

Answer:

\(60\)
