The length of the flower garden is 3 times as great as the width. what are the dimensions of the flower garden

Without any more information we can't find the actual numerical representation of the length and width but we can give an expression that will allow us to find them...

We let the width equal x, so the length is 3x. That would be the dimensions...

length = 3x
width = x

So to find perimeter the expression would be

2(3x) + 2(x) =
6x + 2x =
8x

For the area it would be

a= length × width
a = 3x × x
a = 3x^2

The answer of the above is
