Question

6) The semi perimeter of the rectangular garden is 36 cm. the length of

the garden is 4cm more than its breadth. Find the area of garden​

Answer 1

Step-by-step explanation:

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

Hope it helps you mate..

Answer 2

Step-by-step explanation:

let the breadth of garden be x cm

length of garden = (x + 4) cm

Perimeter of garden = 36×2

2(x+x+4) = 72

2(2x+4) = 72

2x+4 = 72/2

2x+4 =36

2x =36–4

2x = 32

x = 32/2

x = 16

Breadth of garden = 16 cm

length of garden = x+4

=16+4

=20 cm

Area of garden = length × breadth

= 16 × 20

= 320 cm²
