Question

the breath of a rectangle room is 2/3 of length. if the area of the the room is 2400 square cm. find the perimeter of the room​

Answer 1

Answer:

200cm

Step-by-step explanation:

Let the lenght be x

So breadth 2/3 x

Area = l*b

2400=x*2/3x

2400*3/2 =x^2

3600=x^2

x=60

L=60 b=2/3 *60=40

Perimeter=2(l+b)

=2(60+40)

=2(100)

Perimeter=200cm
