In the above question, how many square metres of cloth is required to cover all the display boards? What will be the length in m of the cloth used, if its breadth is 120cm?
Given:
Total display boards = 24
Length of display board = 1 + 0.5 [50cm =50/100 m= 0.5m]
= 1.5 m
Breadth of display board = 1 m
Area of one display board = 1 × 1.5
= 1.5 m2
Area of 24 display boards = 24 × 1.5
= 36 m2
36 m cloth is required to cover the display board.
Breadth = 120 cm
= 1.2 m
Area = l × b
l = 36 / 1.2
l = 30 m.
