AREA OF A SQUARE
A square is a polygon with four sides equal and having four angles measured 90 degrees each.
Illustration:
To get the area of a square, simply multiply each side twice. that is side * side.
Formula:
A = s*s
Problem:
1. Find the area of a square with side measures 4 meters.
Given:
s = 4 m
Required: Area
A= s*s
A = 4 m * 4 m
A = 16 sq. m. (answer)
2. From the figure below, find the area of a square.
Figure:
s = 6 inches
Required: Area
A= s*s
A = 6 in * 6 in
A = 36 sq. in. (answer)
3. A square has a diagonal measures 25 inches. What is the area of a square? (See illustration below).
Illustration:
This is special case. We need to apply Phytagorean theorem here. Click the link to see it.
Given:
s = 5 inches
Required: Area
A= s*s
A = 5 in * 5 in
A = 25 sq. in. (answer)
