Question

Please need help on this

Answer 1

E. 46

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

I hope this helps!

Answer 2

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.
