Question

Find the dimensions of a rectangle with perimeter 100 m whose area is as large as possible. O 20 m by 20 m O None of the choices O 10 m by 10 m O 30m by 30 m O 25 m by 25 m

Answer 1

25 m by 25 m

Explanation:

The formula for the perimeter of a rectangle is given by:

P = 2l + 2w, where

• P is the perimeter,
• l is the length,
• and w is the width.

All the answers have the same dimensions, so the perimeter is simply 4 * one of the dimensions (the perimeter is the sum of all the sides of a rectangle, which is why we can use 4 * one of the dimensions).

You can only get a perimeter of 100 m with the last answer as 25 + 25 + 25 + 25.
