Question

a hall is 7.2 m long and 6m broad.the floor is carpeted leaving a margin of 45 cm on all sides. What is the area to be carpeted

Answer 1

To calculate the area to be carpeted, first calculate the dimensions of the carpeted area within the hall. Subtract twice the margin (since there are two sides with margins) from the length and width of the hall. Then, multiply the adjusted length by the adjusted width to find the area to be carpeted.

Adjusted Length = 7.2 m - 2 x 0.45 m
Adjusted Width = 6 m - 2 x 0.45 m

Once you have the adjusted length and width, multiply them together to find the area to be carpeted in square meters.
