Question

7. The table measures 120 cm in length and 90 cm in breadth. If you need an overhang of 6 cm
all-round the table, what should be the dimensions of the cloth you would need? Calculate
the areas of your table top and of the cloth you chose for it.
​

Answer 1

Answer:

The table will have the dimensions, length =4−2(0.25)=3.5m

Breadth =2−2(0.25)=1.5m

Area of the table top =l×b=3.5×1.5=5.25m

2

Cost of polishing the top of the table at Rs2.25 per square meters

=Rs2.25×5.25=Rs.11.8125=Rs.12

Answer 2

Answer:

The table will have the dimensions, length =4−2(0.25)=3.5m
