Question

The square whose area is $100m^2$ is divided into 5 rectangles of equal area. If the length of the rectangle is 10 m, then find the breadth.

• A. $2m$
• B. $\frac{1}{2}m$
• C. $4m$
• D. $\frac{2}{5}m$

Answer 1

The correct option is A

$2m$

Area of square $=100m^2$

Number of rectangles formed = 5

Area of each rectangle $=\frac{Areaofsquare}{Numberofrectanglescreated}=\frac{100}{5}=20m^2$

length of rectangle = 10 m

breadth, b = ?

Area of rectangle = length x breadth

20 = 10 x b

$b=\frac{20}{10}=2m$

The breadth of the rectangle is 2 m
