Mensuration Practice Test 1

In a rectangle,
Length = 60 m
Breadth = 40 m
Area of the rectangle = l × b
= 60 × 40 = 2,400 m2

Dimension of the rectangle increased = 200%
New length = 60 + 120 = 180 m.
Breadth = 40 + 80 = 120 m
Area of the rectangle = l × b
= 180 × 120 = 21,600 m2
Area increased =

19200

2400

× 100 = 800 %
