1. Area of
combined figures

2. Example 1:
Anand bought a square plot of side 45 m, adjacent to this Akash bought a
rectangular plot of length 50 m and breadth 60 m. Both paid the same amount.
Who is benefited ?
Solution
Given:
For square plot(1) Side(S) = 45m
For Rectangular plot(2) Length(L) = 50 m & Breadth(B) = 60 m
Area of square plot of Anand (1) = S x S = 45 x 45 = 2025 m2
Area of Rectangular plot of Akash (2) = L x B = 50 x 60 = 3000 m2
Area of rectangular plot(3000 m2) is more than the square plot(2025 m2)
So, Akash is benefited

3. Example 2:
Which has larger area? A right triangle with the length of the sides containing
the right angle being 55 cm and 40 cm or a square of length 80 cm.
Solution
Given:
Side of square (S) = 80 cm
Dimensions of triangle (B) & (H) = 55 cm and 40 cm
Area of square = S x S = 80 x 80 = 6400 cm2
Area of Triangle =
Area of square(6400 cm2 ) is more than the area of triangle(1100 cm2 )
So, Square has larger area 20
x b x h =
x 55 x 40
= 55 x 20 = 1100 cm2

4. Try these
Mani bought a triangular plot of base 30 m and height 23 m, adjacent to this
Ravi bought a rectangular plot of length 60 m and breadth 20 m for the same
price. Find out who is benefited and how many sq. m. are more for him?
