The poster has a border whose width is 2 cm on each side. 1 A piece of wood was cut such that its length becomes 16 ft and width. Then, the total cost of carpeting for 60 square meters : Area and Perimeter of Rectangle - Word Problems. The cost of carpeting is $15 per square meter. To find the area of the regular pentagon, substitute 4 for apothem and 30 for perimeter in the formula (1).

Because the floor of the room is in the shape of regular pentagon (regular polygon), we can use the formula for area of a regular polygon to find the area of the floor. Area and perimeter worksheets: rectangles (with measurement units) In these worksheets, students calculate for the perimeter and area rectangles given the lengths or two adjacent sides. To find the total cost of carpeting the floor of the room, we have to know its area. If the cost of the carpeting is $15 per square meter, find the total cost of carpeting the floor of the room whose shape is a regular pentagon shown below.
