Question

Perimeter of a rectangular play ground is 32 meter and its length is 4 m more than its breadth .find the length and breadth of the rectangular play ground.

Answer 1

Answer:

we know that , perimeter of rect=2 (l+b)

Step-by-step explanation:

here,l=b+4

therefore, 2 (l+b)=32

2 [(l)+(l-4)]=32

2 (2×l-4)=32

2×l =20

l=10m

now substitute the value in eq 1

l=b+4

10= b+4

b=6 cm

Answer 2

Answer:

length=10m

breadth=6m

Step-by-step explanation:

let the breath is equal to X

then the length will be equal to X + 4

then the perimeter of the rectangle = 2( l + b )

32 = 2(x+x+4)

32 = 4x+8

4x = 32-8

4x = 24

x = 24/4

x = 6

then the length will be equal to X + 4 = 6+4 = 10

then the breadth will be x = 6
