Question

A rectangle measures fifteen
centimetres by four centimetres.
What is its area?

Answer 1

60 centimeters²

Explanation:

side length a = 15 cm

side length b = 4 cm

diagonal p = q = 15.52417469626 cm

perimeter P = 38 cm

area A = 60 cm2

Answer 2

A = 60 cm²

Explanation:

The area (A) of a rectangle is calculated as

A = lb ( l is length , b is breadth )

Here l = 15 and b = 4 , then

A = 15 × 4 = 60 cm²
