Question

The length of a rectangle is twice its breadth. If its perimeter is 60 cm, find the breadth of the rectangle.​

Answer 1

Answer:

breadth = 10 cm

Step-by-step explanation:

let the breadth of the rectangle be x

length of the rectangle = 2x

perimeter = 60cm

$2(l + b) = 60 \\ \\ 2(2x + x) = 60 \\ \\ 3x = 60 \div 2 \\ \\ 3x = 30 \\ \\ x = 30 \div 3 \\ \\ x = 10$

length= 2x= 20cm

breadth =10cm
