Question

The cover of a jacuzzi is a regular pentagon. If the side measures 2.5 feet and the apothem is 1.7 feet, find the area of the lid used to cover the Jacuzzi

Answer 1

For those who have the choices it would be 10.6

Answer 2

we know that
[area of a regular pentagon]=5 *[Area of triangle with side 2.5 ft and height (apothem) 1.7 ft]

[area of a regular pentagon]=5 *[2.5*1.7/2]-------------> 5*[2.125]-----> 10.625 ft²

the answer is 10.625 ft²
