Step-by-step explanation:
Half of the perimeter = 40m
Total perimeter =40×2
= 80m
Let the breadth =x
then the length =x+4 (length is 4m more than its
breadth)
Perimeter of a rectangle =2(l+b)
80m = 2((x+4)+x)
80m =2(2x+4)
80m÷2 =2x+4
40m=2x+4
40m-4=2x
36m=2x
x =36÷2
= 18m
b=18m
l=x+4
=18+4
=22m
ur answere dear
have a fantastic day
