Question

length of a rectangle exceeds its breadth by 4 m. If the perimeter of the rectangle is 72m,find its length and breadth.

Answer 1

Answer:

breadth of rectangle=16m

length of rectangle=20m

Step-by-step explanation:

let the breadth of rectangle be x

then, length of rectangle is x+4

given perimeter of rectangle=72m

but, perimeter=2(l+b)

72=2(x+4+x)

2(2x+4)=72

2x+4=36

2x=32

x=16

breadth of rectangle=x=16m

length of rectangle=x+4=20m

Answer 2

Answer:

According to Question:-

Breadth = 4m

Length = B + 4

Perimeter = 72

____________

2(b + b + 4) = 72

b + 2 = ${\cancel{\dfrac{72}{4}}}$ = 36

B = 36 - 2

Breadth = 34

Length = 34 + 4 = 38
