Question

A square has an apothem measuring 2.5 cm and a perimeter of 20cm. What is the area of the square, rounded to the nearest square centimeter?

Answer 1

area of a regular polygon

A = (1/2)ap

a = apothem p = perimeter

in this case we know both, so the area of the square is just
`\bf A=\cfrac{1}{2}(2.5)(20)`.

Answer 2

25ft

Explanation:

1/2(2.5)(20)

2.5(10)= 25
