The perimeter of a rectangle is 30meter. If the length is twice the width, what is the width?
1 answer:
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.
<span>Then the area of the rectangle is 72 square feet.</span>
<span>I am 100% sure that that would be the answer!!</span>

Answer:
Step-by-step
Create an algebraic equation. 6N-12. 6x1 - 12 = -6. So -6 is the first term.
6x10-12 = 48. So 48 is the 10th term
