Question

The area of a square is 100cm2 . What is the length of each side

Answer 1

Area of square = 100 cm^2

Side × Side = 100 cm^2

Side^2 = 100 cm^2

Side = 10

Hence length of each side of square is 10 cm .

Answer 2

Given:

• Area of the square = 100 $cm^2$

To Find:

• The length of each side of the square.

Solution:

• We know that the area of a square = side*side = $side^2$ = a*a  
• $a^2$ = area of the square → (1)
• Where 'a' is the side of the square.
• Substitute the value of the area in equation (1) we get
• $a^2$ = 100
• a = √100 = 10 cm (The length of all the sides of a square are equal)

∴The length of each side of the square is 10 cm.
