Question

the length of the rectangle is one and half times its breath. if the perimeter of rectangle is 100 cm find its breath and rectangle
​

Answer 1

Answer:

Breadth = 20 cm

Length = 30 cm

Explanation:

Let breadth of rectangle be x

Therefore length of the rectangle will be 3x/2

Perimeter = 2*(l+b)

⇒100=2*(x+(3x/2))

100= 2*((2x + 3x)/2)

100 = (2*5x)/2

2 and 2 will be cancelled out

5x = 100

x = 100/5 = 20 cm

b = 3/2*x

b=3/2*20

b = 30 cm
