Question 5
What is the area of the shaded region of the following rectangle?
Each small rectangle is 4 cm x 2 cm.
Solution
| Area of larger rectangle is: |
|
L x W |
|
= |
24 x 8 |
| |
= |
192 cm². |
| Area of smaller rectangle is: |
|
L x W |
| |
= |
4 x 2 |
| |
= |
8 cm². |
| Therefore shaded area |
= |
Area of larger rectangle – Area of smaller rectangle |
| |
= |
192 – 8 |
| |
= |
184 cm². |
| The area of the shaded region is 184 cm². |
