Question

Find The Area of the Shaded Region

Answer 1

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:

Find the area of the 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
