Question

OR'
1. The area of the rectangle is 171 square metre. If the length is 19 metre find its breadth. Also find its
perimeter.​

Answer 1

Step-by-step explanation:

area of rectangle = 171

l = 19

b = x

Area of rectangle = l × b

171 = 19 × x

171/19 = x

x = 9

Given:-

Area of the rectangle = 171 m²

Length of the rectangle = 19m

To find breadth:-

Breadth = (Area/Length)

= 171/19

= 9m

∴ Breadth = 9m✔

Now, the perimeter of the rectangle = 2(l+b)

⇒ 2(19+9)

⇒ 2 × 28

⇒ 56m

∴ Perimeter = 56m✔
