Question

The area of the entire figure below is 111 square unit.The area of the entire figure below is 111 square unit.

Answer 1

Looking at the image, the width of the rectangle is 7 small rectangles and the length is 9 small rectangles, therefore the area of 1 square unit is equal to 9 * 7 = 63 small rectangles.

From these small rectangles, an area of 5 * 4 = 20 small rectangles is shaded.

Therefore the shaded area is calculated as:

`(20)/(63)\cdot1\text{ square unit}=(20)/(63)\text{ of a square unit}`
