Answer:

pls mark me as brainlist if you will find my answer corret.

Step-by-step explanation:

The perimeter of a rectangular field = 180m

Breadth  = 30m

Use the formula of perimeter to find length

Perimetre = 2(l+b)

180m = 2*(l+30m)  

180/2 = l+30

90 = l +30

90 - 30 = l

The length will  be = 60m
