Question

The diagram shows a square with perimeter 20cm.work out the percentage of the area inside the square that is shaded

Answer 1

16.25 cm squared

Explanation:

20 ÷ 4 = 5

5 - 3 = 2

5 - 3.5 = 1.5

1.5 × 5 = 7.5

2 × 5= 10

7.5 ÷ 2 = 3.75

10 ÷ 2 = 5

3.75 + 5 = 8.75

5 × 5 = 25

25 - 8.75 = 16.25
