Question

5. Half the perimeter of a rectangular garden, whose length is 4 m more than its width, in

36 m. Find the dimensions of the garden​

Answer 1

Step-by-step explanation:

length=20m

breadth=16m

let the length be x

let the breadth be y

given that the half the perimeter of garden is 36

then, 1/2{2(l+b)}=36

or x+y=3

x+y-36=0 (eq1)

given that the length is 4m more than its width

then, length=4+breadth

or x=4+y (eq2)

solving (eq1)

then x+y-36=0

x=36+y (eq3)

putting (eq3) in (eq2)

then x=20 and y=16
