Question

A star is cut from 1 cm grid paper.

What is the approximate perimeter and area of the
star?
The perimeter is about
cm.
The area is about
cm2

Answer 1

The answer is 16 cm

Explanation:

If the area was 16cm^2 before, then each side was 4 cm long since each side of a square is equal, and the area for a square is the length of the sides squared. The square root of 16 is 4, so that is why the sides were 4 cm. When you make each side 1 cm shorter, they're now all 3 cm. 3^2 is 9, so the new area is 9 square centimeters.
