Question

half the perimeter of a rectangular garden, whose length is 4m more than its width, is 36m. find the dimensions of the garden.

Answer 1

l+b=36
b+4+b=36
2b=32
b=16
l=20

Answer 2

Let the breadth be x
therefore, length =x+4

semi perimeter-2(l+b)/2=l+b

l+b=36(given)
x+x+4=36
2x=32
x=16

Breadth=16m
Length=20m
