Question

The length of a rectangle is 1cm more than two times its breadth. Its perimeter is 80cm.

What is its length and breadth ?
​

Answer 1

Therefore breadth = 13 cm and length = 27cm.

Answer 2

Step-by-step explanation:

let breadth be x

then

length will be = 2x+1

perimeter of rectangle= 2(length+breadth) =80cm

2((2x+1)+x) =80 cm

2(3x+1)=80 cm

6x+2= 80cm

6x= 80-2 cm

x= 78÷6 cm

x= 13 cm

breadth =13 cm

length = 2×13+1

= 27 cm
