Question

The length of a rectangle of seven times its breadth. If the perimeter of the rectangle is 96m.Find its length and breadth​

Answer 1

Answer:

length=42 , breadth=6

Step-by-step explanation:

l= 7x

b=x

2(l+b)= 2(7x+x) = 96

2(8x) =96

16x= 96

x=96/16

x=6cm

then length=42cm

breadth=6cm

Answer 2

Step-by-step explanation:

let the breadth of a rectangle is X meter.

(B=X)

so length will be 7 x X =7X meter.

( L= 7X )

perimeter of rectangle :- 2 (L+B)

given perimeter of rectangle is 96 m.

according to question:-

2(X+7X) = 96 meter

2(8X)= 96 meter

8X = 48 meter

X= 6 meter

Therefore;

Length:- X = 6 meter

Breadth:-7X =7x6 = 42 meter.
