Answer:
Area= 44093.75m^2
Length= 212.5m
Breath= 207.5m
Step-by-step explanation:
Given:-
Perimeter = 840 m
length = (b+5)
breath = b
Solution:-
perimeter= 2(l+b)
2(b+5+b)= 840m
2b+5 = 840/2
2b+5 = 420
2b= 420-5=415
breadth (b)= 415/2= 207.5m
length (l)= (b+5)= 207.5+5= 212.5m
Area= l*b
207.5*212.5
=44093.75m^2
