The area of a rectangle is length x width. In the special case of a square, length is the same as width, so you multiply (in this case) 5 x 5.
It is 25 square cm

25 square centimetres !
20cm/4sides = 5cm 5cm*5cm = 25cm^2
25 square centimeters.
50 square centimetres
The area was approx 19.6 square units.
Area = 5*5 = 25 square cm
To determine how many 5cm x 5cm squares can be cut from a 20cm x 40cm card, first calculate the area of the card, which is 20cm x 40cm = 800cm². The area of one square is 5cm x 5cm = 25cm². Dividing the area of the card by the area of one square, 800cm² ÷ 25cm², gives you 32 squares.
78.5 square cm
Each side is 5cm
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.
