Question

The length of a rectangle is 1cm more than two times it's breadth.it's perimeter is 80cm.what is its length?

Answer 1

Answer:

length = 27cm

breadth = 13 cm

Step-by-step explanation:

let the breadth be x

length will be 2x + 1

perimeter of rectangle = 2(l + b) = 80

2(2x + 1 + x)= 80

3x + 1 = 80/2

3x + 1 = 40

3x = 40 - 1

3x = 39

x = 39/3

x = 13

length = 2x + 1 = 2(13) + 1 = 26 + 1 = 27
