Question

in a rectangle of perimeter 22cm ,and side7 cm longer than the other .what are the length of the sides?​

Answer 1

Answer:

let breadth of the perimeter is x cm

so length=(x+7) cm

so,

2(x+7+x)=22

=> 2x+7=22/2

=> 2x=11-7

=> x=4/2

=> x=2

so breadth is 2 cm and length is (2+7)cm=9 cm

Answer 2

Answer:

let the breadth be x

So, length = (x+7)

Perimeter of Rectangle= 2×(l+b)= 22cm

= 2×(x+7+x)= 22cm

= 2×(2x+7)= 22cm

= 2x+7= 22/2= 11

2x= 11-7= 4

x= 4/2

x= 2
