Answer:
Length of the rectangle is 5.2 cm.
Breadth of the rectangle is 2.5 cm.
Area of a rectangle = l × b
= 5.2 cm × 2.5 cm = 13 sq cm
∴ The area of the rectangle is 13 sq cm.
(2) Length of the rectangle is 2.1 m.
Breadth of the rectangle is 1.5 m.
Area of a rectangle = l × b
= 2.1 m × 1.5 m = 3.15 sq m
∴ The area of the rectangle is 3.15 sq m.
(3) Length of the rectangle is 3.5 m.
Breadth of the rectangle is 1.2 m.
Area of a rectangle = l × b
= 3.5 m × 1.2 m = 4.2 sq m
∴ The area of the rectangle is 4.2 sq m.
