Question

If the area covered by the colored region, is 100 sq. cm, what is side(in cm) of each square in the grid?

• A. 1
• B. 4
• C. 2
• D. 25

Answer 1

The correct option is C 2


Number of squares fully or more than half covered = 25
Total area covered by the colored region = 100 sq. cm
Area of each small square = 100 ÷ 25
= 4 sq. cm
Side of the square = 2 cm
