Question

(vii) Find the breadth of a rectangular plot of land, if its area is 440 m2

and the length is 22 m. Also, find its

perimeter.​

Answer 1

Step-by-step explanation:

length is given= 22 m

let breadth is = x

area= 440 m²

now,

area = length × breadth

440 = 22 × x

x=440/22

X= 20

so breadth= 20 m

perimeter = 2(l+b)

=2(20+22)

=2×42

=84m

so , breadth= 20 m and perimeter= 84m

Answer 2

Given that,

• Area of the rectangular plot = 440 m²
• Length of the rectangular plot= 22 m

We know that,

• Area of the rectangle= (Length × Breadth)
• 440 = 22 × Breadth
• Breadth = $\frac{440}{22}$
• Breadth = 20 m

$\rightarrow$ Perimeter of the rectangle = 2 (Length + Breadth)

• 2 (22 + 20)
• 2 × 42
• 84 m

$\therefore$ The perimeter of the rectangular plot is 84 m
