Question

the length of a rectangle is three times its breadth.if the area of the rectangle is 1875square cm. find its perimeter.

Answer 1

HEYA!!

Let the breadth of the Rectangle be X cm.

Then Breadth of Rectangle = 3 ( X ). = 3X cm.

Area of Rectangle = L • B

Area of Rectangle given : 1875 cm^2

Putting in the Formula ,

1875 = 3X • X

3X^2 = 1875

X^2 = 1875 / 3

X^2 = 625

X = 25 cm.


➡Breadth Of Rectangle = 25 cm.

➡Length of Rectangle = 25 ( 3 ) = 75 cm.


✨Perimeter of Rectangle = 2 • ( L + B )

= 2 ( 25 + 75 )

= 2 ( 100)

= 200 cm.
