The perimeter of the rectangle is found by multiplying 2 times the length, and then adding to that 2 times the width. The reason for that is that the opposite sides of a rectangle are congruent.<\/p>\n<p>If you are trying to find the distance around a rectangle, then you have two sides that have the same length and then two sides that have the same width. If you just multiply 2 times the length and 2 times the width, and add those together, then you\u2019ll find the perimeter of the rectangle. Let\u2019s look at our example.<\/p>\n<p>What is the area and perimeter of a rectangle with a 5ft length and a 3 ft width. We\u2019ve been given a word problem, but we already have this nice picture drawn here of a rectangle. What we can do is we have a 5ft length so we get rid of this l and put that our length is 5ft. Then our width is 3ft, we can get rid of this w and put that our width is 3ft.<\/p>\n<p>Now we\u2019re asked to find area, we should start with our area formula. Area = lw.  Area = 5ft \u00d7 3ft. The area is 5 times 3 is 15, ft times ft is ft<sup>2<\/sup>. Our area is 15ft<sup>2<\/sup>. The perimeter. Again, we need to start with our formula. Perimeter is 2 times the length plus 2 times the width. Our perimeter is 2 times, then our length was 5ft. We substitute 5ft for our length plus 2 times, and our width was 3ft. Substitute 3ft for width. P= 2(5ft) + 2(3ft).<\/p>\n<p>Then we need to follow PEMDAS, which means we need to multiply before we add. The perimeter is 2 \u00d7 5ft = 10ft, plus 2 \u00d7 3ft = 6ft. Finally, we add these together and find the sum. 10ft + 6ft = 16ft.  It would be 16ft all the way around our rectangle.<\/p>\n<\/div>\n<\/div>\n\n","protected":false},"excerpt":{"rendered":"<p>Finding the Area and Perimeter of a Rectangle<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"open","template":"","meta":{"footnotes":""},"class_list":{"0":"post-4373","1":"page","2":"type-page","3":"status-publish","5":"page_type-video"},"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO Pro 5.0.2.1 - aioseo.com -->\n\t<meta name=\"description\" content=\"This video tutorial helps explain the basics of Area and Perimeter of a Rectangle.
