Answer 1

In your question the ANSWER will be 40

PLEASE MARK MY ANSWER AS BRAINLIST

Step-by-step explanation:

let the number be x

ratio=7:5

So, length 7x

breadth 5x

perimeter=2(l+b)

》7x+5x=63

》12x=63

》x=63÷12=5.25

》So, the length=7(5.25)=36.75

breadth =5(5.25)=26.25

Hence, the breadth of the rectangle ground is 26.25m.

Area= (36.75×26.25)=964.6875
