Question

find the perimeter of the rectangle. give an exact answer if possible. otherwise, give an estimate. estimation must be used. the perimeter is about m an exact answer can be found. the perimeter is m

Explanation:

Step1: Recall perimeter formula

The formula for the perimeter P of a rectangle is $P = 2\times(\text{length}+\text{width})$. Let the width $w = 5$ m and length be $l$. So $P=2(l + 5)=10 + 2l$.

Step2: Example calculation

If $l = 10$ m, then $P=2\times(10 + 5)=2\times15 = 30$ m.

Answer:

An exact answer can be found. The perimeter is 10 + 2l m, where l is the length of the rectangle. If we assume the length is, for example, 10 m (not given in the problem but for illustration), the exact perimeter is 30 m.
