Question

The length of a rectangle is 2cm more than thrice its breadth.If its perimeter is 68m , find the dimensions of the rectangle.​

Answer 1

ANS-

Let the breath be x

So the length will be 3x+2

perimeter of rectangle = 2(l+b)

= 2(x+3x+2)= 68

2x+6x+4= 68

8x+4= 68

8x= 68-4

x= 64/8

= 8

Breath = 8

length= 3×8+2= 26

Hope it helps
