Question

The length of a rectangular field is 8 meters less than twice its breadth. If the perimeter of
the rectangular field is 56 meters, find its length and breadth?​

Answer 1

Answer:

let the breadth be x

then

length =2x-8

perimeter of rectangle= 2(l+b)

56=2(2x-8+x)

56/2=(2x-8+x)

28=3x -8

28+8=3x

36=3x

36/3=x

12m=x

therefore length (l)=2x-8=2×12-8=16m

breadth (b)= 12 m
