On the occasion of Republic Day, a school organised a poster making competition for
the students of Class-Vl. The topic was 'National Integration. Each child was given
a square sheet of side 60 cm. They had to make a border of width 2 cm using the
coloured tape and the remaining portion had to be divided into four equal portions to
show main teachings of different religions.
(a) Find the length of the coloured tape needed for the border.
(b)
What will be the side of the square into which the sheet has been divided?
(c)
What do you learn from the given situation?
Answers
(a) The 232 cm long tape needed for the border.
(b) The sides of the square into which the sheet has been divided is 28 cm.
Step-by-step explanation:
Length of each sides of a square sheet = 60 cm.
Students had to make a border of using the colored tape.
Width of the tape = 2 cm
(a) Length of tape used for 2 parallel sides = 60 × 2 = 120 cm
But now other two sides left its length 4 cm less = 60 - 4 = 56 cm
For other two sides length of the tape needed = 56 × 2 = 112 cm
∴ Total tape needed for the border = 120 + 112 = 232 cm
The 232 cm long tape needed for the border.
(b) After making border of 2 cm each side the remaining lengths of the squared sheet = 56 cm
The sides of the square into which the sheet has been divided =
= 28 cm
The sides of the square into which the sheet has been divided is 28 cm.
(c) We can understand this problem by the attached figure.

(b) After making border of 2 cm each side the remaining lengths of the squared sheet = 56 cm
The sides of the square into which the sheet has been divided = \frac{56}{2}
