Answer 1

Answer:

Dimension of rectangle of all sides equal (square) = 5 meter

Maximum area = 25 m²

Step-by-step explanation:

Note:

• A wire of same length forms maximum area,, when it has given the geometry of circle.
• And if it is given rectangular shape than maximum are is when it is square.

Now let's start:

Perimeter of square = Length of wire = 20m

4a = 20

a = 5m (dimension of each sides with max. area)

Area of square = a² = 5² = 25 m²

Hope it helped!
