To find side b and c, we use the property that the opposite sides of a rectangle are
always the same in size.
Hence, a = c = 4 cm and d = b = 3 cm.
4. When the area of the square is given, the formula for finding the side of the
square is as follows:
Example: The area of the square shown below is 36 square inches. What is the
length of one of the sides?
Area of a square = 36 square inches = Side x Side (Area = S x S, where both
the sides of the square are equal)
A = S x S
36 square inches = 6 inches x 6 inches
Thus, the length of each side of a square is 6 inches.
5. When the area and length of a rectangle is given, the formula for finding the
breadth is as follows:
Breadth = Area/Length
6. When the area and breadth of a rectangle is given, the formula for finding
the length is as follows:
Length = Area/Breadth
Example: Find the length of a rectangle whose breadth is 5 cm and area is 90 sq.
cm.
Solution:
Breadth (b) = 5 cm,
