Question

lenght of a rectangle is 7 times its breadth if perimeter of rectangle is 96.find its lenght and breadth

Answer 1

here is your answer by Sujeet,
Let to be Length =x
Let to be breadth=x

then,
A/q
when 7 times of length more than breadth....

Again,
Length=7x
Breadth =x

Now,

Perimeter of rectangle=2(l+b)=96
2(7x+x)=96
2(8x)=96
16x=96
x=96/16
x=6

then
Length to be 7x=7*6=42
Breadth to be x=6



that's all.....

Answer 2

let b=x,then l=7x
pm=2(l+b)
96=2(x+7x)
96=16x
16x=96
x=6
l=7×6=42m
b=6m
