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.
