Question

the perimeter of a rectangular plot is 840 m . and if its just length exceeds breadth by 5m find the length and breadth of the plot , also find its area.​

Answer 1

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
