171 +727 round it or compatible numbers to estimate the sum
djyliett [7]
171 is rounded to 200 as it is closest to 200 than 100

The perimeter of a rectangular
cupoosta [38]

Answer:

5 ft

Step-by-step explanation:

Since we have a rectangle, we know for sure that perimeter = double the width and double the height. Algebraically, that looks like:

P = 2W + 2H

Let's sub in the given values, P and W:

18 = 2(4) + 2H

Now, let's solve for the height, H:

18 = 8 + 2H

10 = 2H

10/2 = H

<u>5 = H</u>

I hope this helps!
