Question

How do I solve for the area of the shaded region?

Answer 1

We know that the diameter of the circles is 10 units so we find the area of them which is π r² or 3.14 * 5² which equals about 78.5. since there are two circles we multiply that by 2 which is 157.

We then find the area of the rectangle which is 10 times 20 which is 200.

We then do 200 - 157 which is 43

43 units squared

Answer 2

How To Find The Area Of The Shaded Region?

Step 1: Find area of inner shape.

Step 2: Find area of outer shape.

Step 3: Area of shaded region = area of outer shape – area of inner shape

Example 2:

Find the area of the shaded region:

area of shaded region

Solution:

Step 1: Find area of inner square = 2 cm × 2 cm = 4 cm2

Step 2: Find area of outer shape = (2 cm × 3 cm) + (10 cm × 3 cm)

= 6 cm2 + 30 cm2

= 36 cm2

Step 3: Area of shaded region = area of outer shape – area of inner square

= 36 cm2 – 4 cm2

= 32 cm2
