Question

Find the breadth of rectangular plot of land whose area is 440 square metre and the length is 22 m

Answer 1

$area \: of \: the \: rectangle \: = 440 {m}^{2} \\ length = 22m \\ area \: of \: the \: rectangle = l \times b \\ 440 = 22 \times b \\ b = \frac{440}{22} = 20$

Answer 2

Given :

1. Area = 440m².
2. Length = 22m.

　

To find :

• What is the breadth and rectangular plot of land.

　

Using formula :

★ Area of Rectangle = Length × Breadth.

　

Calculations :

→ L × B = 440

→ 22 (B) = 440

→ B = 440/22

→ B = 20 m

　

→ P = 2 (L + B)

→ P = 2 (22 + 20)

→ P = 2 (42)

→ P = 84 m
