Question

Calculate the areas of these rectangles
​

Answer 1

The answer is below

Explanation:

A rectangle is a quadrilateral (four sides) with two pairs of equal opposite and parallel sides. All the four angles in a rectangle are equal to 90° (right angle). The diagonals of a rectangle are equal and bisect each other.

The area of a rectangle = length * breadth

a) Area = length * breadth = 8 cm * 3 cm = 24 cm²

b) Area = length * breadth = 5.2 cm * 7.7 cm = 40.04 cm²
