Answer:
72 square feet
Step-by-step explanation:
the length is 12 and the width is 6. 12+12=24 and 6+6=12. 24+12=36
so 12x6= 72
Answer:
72 square feet
Step-by-step explanation:
First, write the length of the rectangle in terms of the width, given that l is length and w is width. From the information given, l can be writen as 2w.
The perimeter of a shape is just the length of all the sides added up. For this rectangle that length would be: w+2w+w+2w. which simplifies to 6w. Now we get 6w=36, because we know from the information given that the perimeter of the rectangle is 36 feet. Dividing both sides by 6 gives w=6, and 2w (the length) = 12.
Finally, multiply the length by the width (12x6) for the area of the rectangle.
Hope this helps!
