Question

The perimeter of a rectangle is 28.8 centimeters. The length of the rectangle is twice as long as its width. Find the length and width of the rectangle.

Answer 1

"Length is twice width."

So let width = X , then Length = 2x.

Now perimeter is 28.8

so 2(length + width) = 28.8

2(x+2x) = 28.8

2.3x = 28.8 hence 6x = 28.8 .

solve for x.
