Answer:
The perimeter of a shape is the sum of the measurements of all sides. Since a rectangle have equal lengths and widths, you can just add the numbers twice.
So, 15 + 15 + 8 + 8. So the perimeter is 46 cm.
Answer:
E. 46
Step-by-step explanation:
The perimeter of a square or rectangle can be found by using the following formula:
(length + legnth) + (width + width) = perimeter
Our length here is 15 and the width is 8, so substitute the values into the equation.
(15 + 15) + (8 + 8) = perimeter
Now solve
(15 + 15) + (8 + 8)
(30) + (8 + 8)
(30) + (16)
=46
Therefore, the perimeter (and answer) is E. 46
