First, we must deal with dimensions that include both feet and inches.\r\n<div class=\"textbox key-takeaways\">\r\n<h3>CALCULATING AREA WITH FEET AND INCHES<\/h3>\r\nWhen calculating the area of a rectangular room, it is important to <strong>convert the dimensions into feet only before multiplying<\/strong>.\r\n\r\nFor example, suppose we want to find the area of a rectangular room that is 12 feet 6 inches by 10 feet 3 inches. This can also be written as:\r\n<p style=\"text-align: center;\">12 ft. 6 in. x 10 ft. 3 in. or 12' 6\" x 10' 3\".<\/p>\r\nIt is important to note that 12' 6\" is not 12.6 ft. We must first convert to feet only. Using the table below, we see that 12 ft. 6 in. is 12.5 ft. (or 12' 6\" = 12.5'). Also, 10 ft. 3 in. is 10.25 feet (or 10' 3\" = 10.25').\r\n\r\nTherefore, to find the area of the rectangular room, we multiply 12.5' x 10.25' to get 128.125 square feet (or 128.125 ft<sup>2<\/sup>).\r\n\r\n<a href=\"https:\/\/s3-us-west-2.amazonaws.com\/courses-images\/wp-content\/uploads\/sites\/5548\/2021\/01\/04034741\/Inches-to-Feet.jpg\"><img class=\"alignnone wp-image-5537\" src=\"https:\/\/s3-us-west-2.amazonaws.com\/courses-images\/wp-content\/uploads\/sites\/5548\/2021\/01\/04034741\/Inches-to-Feet.jpg\" alt=\"\" width=\"602\" height=\"355\" \/><\/a>\r\n\r\n<\/div>\r\nWe also need to calculate price per unit for items such as fence, base boards, and crown molding. By first finding the perimeter of the shape and then using the price per unit, we can calculate how much that item will cost.\r\n<div class=\"textbox key-takeaways\">\r\n<h3>PRICE PER UNIT<\/h3>\r\nIf we were to buy 4 oranges for $1.00, the price is $0.25\/orange. In this example, the price is $0.25 per orange, which is the <strong>price per unit<\/strong>. When finding length, units can be inches, feet, yards, miles, etc. When find area, units can be square inches, square feet, square yards, square miles, etc. Think of the word <strong>per<\/strong> as <strong>divided by<\/strong>.\u00a0 So, price per unit is <strong>price divided by unit<\/strong>.\r\n\r\n<\/div>\r\n<div class=\"textbox examples\">\r\n<h3>Example<\/h3>\r\nA certain type of fence cost $931.50 for 75 feet.

You want to put a fence around the entire yard. Find the price to put up this fence if the price of the fence is $23 per foot, which includes installation.\r\n\r\n<strong>Solution<\/strong>: You will first need to find the perimeter (the length of the entire fence). The formula for perimeter, P, is:\r\n<p style=\"text-align: center;\">P = 2 x Length + 2 x Width = 2L + 2W<\/p>\r\nThis fence is 25 feet long, so L = 25 feet. The width is 20 feet, so W = 20 feet. Plugging these numbers into the formula, we get:\r\n<p style=\"text-align: center;\">P =\u00a0 (2 x 25 feet) + (2 x 20 feet) = 90 feet<\/p>\r\nTherefore, the fence is 90 feet long. Now, multiply the 90 feet by $23 per foot to get $2,070.\r\n<p style=\"text-align: center;\">The price to install the 90-foot fence is $2,070.<\/p>\r\n&nbsp;\r\n\r\n<\/div>\r\n<div class=\"textbox tryit\">\r\n<h3>Try It<\/h3>\r\nSuppose you want to create a rectangular space in your backyard for your dog to be able to run around an play.
