Question

The measure of two adjacent sides of a rectangle are in the ratoi 5:3 if the perimeter of the rectangle is 80 m .find its length and breadth

Answer 1

Answer:

Let 5x and 3x be the length and width of the rectangle

Then,

perimeter of rectangle=2(l+w)

=80 =2(5x+3x)

=80/2=5x+3x

=40=8x

=40/8=x

=5=x

Therefore,

length=5x=5×5=25

width=3x=3×5=15

Step-by-step explanation:

Let us proof that this answer is correct

perimeter of rectangle=2(l+w)

=2(15+25)

=2×40

=80
