length of park=

135m=2(l+b)

135m=2(l+60m)

135m÷2=l+60m

67.5m-60m=l

7.5m=l ans

Answer 2

Answer:

The length of the rectangle is 7.5 m.

Step-by-step explanation:

Given :

Perimeter = 135 m

Breadth = 60 m

To find :

Length

Solution :

Let the length be y

We are all familiar with the formula used for finding a rectangle's Perimeter.

★ Perimeter = 2(Length + Breadth)

⇒ 2(y + 60) = 135

⇒ 2y + 120 = 135

⇒ 2y = 135 - 120

⇒ 2y = 15

⇒ y = 15/2

⇒ y = 7.5

Length = 7.5 m

Therefore, the length of the rectangle is 7.5 m.
