Question

perimeter of football ground is 270m if its length is90m then find its breath

Answer 1

Answer:

Perimeter=270m

Length=90m

Breadth=?

Let us take breadth as 'B'

Perimeter=Length+Breadth

270=90+B

270-90=B

B=180m

Therefore,Breadth is 180m

Step-by-step explanation:

Answer 2

Its breadth is 45 m

Step-by-step explanation:

Length of football ground = 90 m

Let the breadth of football ground be x

Perimeter of football ground = 2(l+b)=2(90+x)

We are given that perimeter of football ground is 270m

So,$2(90+x)=270$

$90+x=\frac{270}{2}$

$x=\frac{270}{2}-90$

x=45

Hence Its breadth is 45 m
