It is 25 square cm
Multiply the length of any side by itself ("square" it). To find the are of any rectangle, including a square you multiply the length by the width, e.g. if it is a 5cm square the area is 5x5=25cm2. If it's a rectangle with a 3cm x 5cm the area is 3x5 = 15cm2.
20cm/4sides = 5cm 5cm*5cm = 25cm^2
Just like any other rectangle.Multiply the length by the width.5cm x 5cm = 25 cm2

Each side is 5cm
yes it is. When you're dealing with the Pythagorean theory, a 3,4,5 triangle is a special triangle. For example, if a triangle has side lengths of 3cm and 4cm, then you automatically know that the other side length is 5cm. It also works if the side lengths are 5cm and 4cm or 5cm and 3cm.

Perimeter = sum of all side lengths. For a square, s1 = s2 ... = s4, so Perimeter = 5+5+5+5 = 4(5) = 20cm

A triangle with side a: 7, side b: 7, and side c: 5 cm has an area of 16.35 square cm.
Just like any other rectangle.Multiply the length by the width.5cm x 5cm = 25 cm2
