The perimeter of a rectangle is 30meter. if the length is twice the width, what is the width?

Let the length of the rectangle be L and the width be W.

Given that the length is twice the width, Then :

L = 2W (1)

But we know that the perimeter is 36.

==> 2L + 2W = 36

==> 2L + L = 36

==> 3L = 36

==> L = 36/3 = 12

==> W = 12/2 = 6

Now we will calculate the area:

==> A = L * W = 12* 6 = 72 square feet.

Then the area of the rectangle is 72 square feet.

I am 100% sure that that would be the answer!!

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

your answer would be 12
