Question

Half the perimeter of a rectangular garden, whose length is 4 m more than its width, is
36 m. Find the dimensions of the garden.​

Answer 1

Answer:

Let the width of the garden =x meter

Then length=(x+4) meter

Half perimeter =36 m

So perimeter of garden =(2×36)=72 meters

According to the question

⇒2(l+b)=72

⇒2(x+x+4)=72

⇒2x+2x+4=74⇒4x=64⇒x=16 meters

Hence,the width of the garden =16 meters

The length of the garden =(16+4)=20 meters

Answer 2

Step-by-step explanation:

let breadth of rectangular garden be x

let breadth of rectangular garden be y

ATQ

x+y=36 1.

x=4 +y 2.

• putting the value of x in equation 1

x+y =36

4+y +y =36

2y =36-4

2y = 32

y = 32÷2

y=16

x = 4y

x= 4+16

x=20
