Question

Which one of the following represents the largest area?
A of a circle of radius 3 cm.
B square of side 2 cm.
C rectangle of dimensions 3 cm by 1 cm.
D triangle of base 3 cm and vertical height 4 cm.​

Answer 1

A) Area of a circle = πr^2

=22/7 × 3 × 3

=28.28 cm square.

B) Area of square = side × side

=2×2

=4 cm square.

C) Area of rectangle = 2(l+b)

=2×(3+1)

=2×4

=8 cm square.

D) Area of triangle = 1/2 × base × height

=1/2×3×4

=6 cm square.

Hence A) the area of circle represents the largest area.
