Question

About how much of the area is coloured, if the area of each small square is 1 sq. unit?

• A. 15 sq. units
• B. 14 sq. units
• C. 11 sq. units
• D. 10 sq. units

Answer 1

The correct option is D 10 sq. units

Full squares = 2 (marked as green)

More than Half squares = 8 (numbered in red)


Given each small square is 1 sq. unit

Area covered by full squares
= 2 x 1
= 2 sq. units

Area covered by more than half squares
= 8 sq. units

Approximate area enclosed by the triangle
= 2 + 8
= 10 sq. units
