Find the perimeter and the area of the figure.

Use A = (1/2)(a)(p)

Here a is the apothem and p is the perimeter.

Perimeter = side times length of side.

P = 8(10)

P = 80

To find the area, use the formula above.

A = (1/2)(a)(p)

A = (1/2)(12)(80)

A = 480

I hope this helps.

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
