The length of a rectangle is twice its breadth. If the perimeter is 42m, find the length and breadth.​

Answer 1

Answer:

breadth = 7m

length = 14m

Step-by-step explanation:

Given:-

breadth = b

Length = 2b

perimeter = 42m

b + 2b + b + 2b = 42m

6b = 42m

b = 42/6

b = 7m

breadth = 7m

length = 14m
