Question

This question confuses the absolute hell out of me.

Answer 1

Answer:

144 in²

Explanation:

The area represented by that figure may be calculated as the area of the rectangle with dimensions 18 in × 12 in less the area of the "hole" which has form of triangle with base 18 in and height equal to 12 in - 4in, 8 in.

1. Area of the rectangle

Area = base × height = 18 in × 12 in = 216 in²

2. Area of the triangle with base 18 in and height 8 in.

Area = base × height / 2 = 18 in × 8 in / 2 = 72 in²

3. Area of the side of the step stool:

216 in² - 72 in² = 144 in²

Answer 2

Answer:

144 in^2

Step-by-step explanation:

The area represented by the figure may be calculated as the area of the rectangle with dimensions 18 in × 12

in less the area of the "hole" which has form of triangle with the base 18in and height equal to 12in - 4in , 8in.

1.Area of the rectangle

Area= base× height = 18in ×12in= 216in^2

2. Area of the triangle with base 18 in and height 8 in

Area= Base×height/2 = 18in × 8in/2 = 72 in^2

3.Area of the side of the step stool

(216-72)in^2 =144 in^2
