Question

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

Answer 1

Answer:

20m

Step-by-step explanation:

Let the breadth be x

Therefore length will be 2x

Perimeter = 2(l+b)

60m = 2(2x+x)

60m = 2(3x)

60m = 6x

x = 60m/6

x = 10m

Breadth = 10m

Length = 2x = 2 × 10m = 20m
