Question

the length of a rectangle is 3 times of its breadth find the find the find our parameter is 126 ​

Answer 1

Answer:

L=47.25 cm and B=15.75 cm

Step-by-step explanation:

Given,

Perimeter of rectangle=126 cm

Length is three times the breadth.

Let the length be '3x'

And breadth be 'x'

Perimeter of rectangle=2(l+b)

126=2(3x+x)

126=2(4x)

126=8x

x=126/8

x=15.75

Now, length=3x

l=3(15.75)

l=47.25 cm

b=15.75 cm
