Question

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:

Area =length×breadth

⇒22×(breadth)=440

breadth=20 cm

Perimeter =2(length×breadth)

2(20+22)=2×42=84 m

Answer 2

Given:

Area = 440 m2

Length = 22 m

$breadth \: = \frac{area}{length} = \frac{ {440m}^{2} }{22m} = 20m$

➪Hence,the breadth is 20m

Perimeter = 2[l + b]

= 2 [22 m + 20 m] {Length= 22m , Breadth = 20m}

= 2 × 42 m = 84 m

➪The perimeter is 84 cm
