Answer:
Step-by-step explanation:
We know that a rectangle has four sides - two lengths and two widths. We also know that the lengths are equal and that the widths are equal. Therefore, to find the perimeter of a rectangle, we use:
However, this problem asks to find the area of the rectangle. The area can be found by multiplying length and width (A = L × W).
Using our formula above, we can solve for the length.
(divide everything by 2)
(subtract W in order to solve for L)
(rearrange W to the left - standard equation notation)
The area of a rectangle is solved using the formula A = LW, so we just need to input our values and solve for A.
(distribute the W throughout)
This is your final function. Hope this helps!
