a banquet hall area is in d shape of a rectangle 30m by 20m.part of d area is a concrete square 15m by 15m,the rest is covered with carpet.calculate the area of the carpet.
" d shape" , "d area" ??????
whole area = 30(20) = 600 m^2
area of concrete square = 15(15) or 225 m^2
So d area of d carpet is 600-225 or 375 m^2
thanku so much
To calculate the area of the carpet in the banquet hall, we need to find the area of the rectangle first and then subtract the area of the concrete square.
1. Find the area of the rectangle:
The area of a rectangle is calculated by multiplying its length by its width.
Given that the length of the rectangle is 30m and the width is 20m, we can calculate the area:
Area of rectangle = Length x Width = 30m x 20m = 600 square meters.
2. Find the area of the concrete square:
The area of a square is calculated by multiplying its side length by itself.
Given that the side length of the concrete square is 15m, we can calculate the area:
Area of square = Side length x Side length = 15m x 15m = 225 square meters.
3. Calculate the area of the carpet:
To find the area of the carpet, we subtract the area of the concrete square from the area of the rectangle:
Area of carpet = Area of rectangle - Area of square = 600 square meters - 225 square meters = 375 square meters.
Therefore, the area of the carpet in the banquet hall is 375 square meters.
