Question

The length of a rectangle is four times its width. Twice the perimeter of that rectangle is 160 cm. Find

the length and width of that rectangle. pls answer fast​

Answer 1

Length = 4*5 = 20 cm

Width. = 4 cm.

Answer 2

Explanation:

Given twice the perimeter of rectangle =160

Let width of the rectangle=X

So length of the rectangle =4x

2(perimeter of rectangle)=160

2[2(length+width)]=160

4(4x+x)=160

5x=160/4

5x=40

X=40/8

X=5cm

So length of the rectangle =4x

=20cm

Width of the rectangle =X

=5cm.
