Question

if ratio of sides of a rectangle is 5:4 perimeter of rectangle is 180cm then find area of rectangle.​

Answer 1

Answer:

Let the length be 5x

Breath be 4x

Perimeter=2(l+b)

180m=2(5x+4x)

180m=2(9x)

18x=180m

x=180/18

x=10

Length=5x

=5(10m)

=50m

Breath=4x

=4(10m)

=40m

Now,

Since,Area=l×b

=50m×40m

=2000m^2
