Class 5 Maths | How Many Squares | Practice Problems

Textbook solutions of this chapter can be found here. 

Given below are practice problems that students can do to improve their understanding of this chapter.

1. Find the perimeter and area of the following by counting the square

2. Draw lines and divide the following figures into parts having equal area as directed.

3. Complete the shapes as directed.

Solutions

1. a) Area = 4 (since the number of squares are 4)
Perimeter = 8 (Length of the boundary is known as perimeter)
b) Area = 9 (since the number of squares are 9)
Perimeter = 12
c) Area = 16 (since the number of squares are 16)
Perimeter = 16

4. Since there are 25 squares in the figure, area is 25.
Since the length of the boundary is 20, perimeter = 20
5. Area = 10
Here we can consider the figure as 4 parts.

In the 1 st part, area is the half of 4 squares.
In the 2 nd part, area is the half of 4 squares.
In the 3 rd part, area is the half of 6 squares.
In the 4 th part, area is the half of 6 squares.
Therefore, total area = 2 + 2+ 3+ 3 = 10 square cm
