Question

Kyle draws a quadrilateral with a perimeter of 30 centimetres. What is the maximum possible area of Kyle's shape?

Answer 1

225 square cm.

Explanation:

The maximum possible area of Kyle's quadrilateral occurs when it is a square with side length equal to half the perimeter, which is 30/2 = 15 cm. The area of a square with side length 15 cm is 15 x 15 = 225 square cm.
