Answer 1

Answer:

$26.85$

inches.

Step-by-step explanation:

First, let us split this figure into two parts, a parallelogram and a semi-circle. The perimeter of the parallelogram will be

$5 + 7 + 7 = 19$

inches. We do not add the additional 5 inches due to it being stuck to the semi-circle, and hence that additional 5 inches is not part of the perimeter.

To find the curved perimeter of the semi-circle, we use the formula

$\pi d$

and then divide it by two as the above formula is used for a whole circle. The diameter is 5 inches and thus the curved perimeter is

$\frac{1}{2} \pi(5) = 2.5\pi$

The total perimeter is then

$19 + 2.5\pi$

Using a calculator, we get

$26.85398...$

and the answer is

$26.85$

inches when corrected to the nearest hundredth.
