Elena-2011 [213]
You can set this up as 2 fractions equal to each other, like ratios.

18/11=108/x

Cross multiply and you get 18x=1,188

Now divide both sides by 18 and get x.

x=66.

If the height of the building is 108ft, the width is 66ft.

A regular pentagon has an apothem of 7.3 inches and a perimeter of 53 inches. What is the area of the pentagon? Round your answe
zvonat [6]

Answer:

Area pf the regular pentagon is 193inch^{2} to the nearest whole number

Step-by-step explanation:

In this question, we are tasked with calculating the area of a regular pentagon, given the apothem and the perimeter

Mathematically, the area of a regular pentagon given the apothem and the perimeter can be calculated using the formula below;

Area of regular pentagon = 1/2 × apothem × perimeter

From the question, we can identify that the value of the apothem is 7.3 inches, while the value of the perimeter is 53 inches

We plug these values into the equation above to get;

Area = 1/2 × 7.3× 53 = 386.9/2 = 193.45 which is 193inch^{2} to the nearest whole number
