Question

8) The length of a rectangle is four times the width. If its perimeter is 50m, find the length of
the rectangle.​

Answer 1

Step-by-step explanation:

let the breadth is X cm

then length will be 4X

now according to question

perimeter=2(length+breadth)

=2(4X+X)

perimeter=10X

now given perimeter is 50m

so

50=10X

so X=50/10

X=5m

me as breadth is 5m

length is 4 times of breadth

so length =4*5=20m

mark me as brainliest if u are happy
