Math Central is supported by the University of Regina and the Imperial Oil Foundation. Therefore, the area of the rectangle is the area covered by its outer boundaries. The fact that there are two solutions means that you might have two rectangles, one rectangle and another with dimensions that don't make sense or two situations that don't give rectangles. Area is the region covered by a two-dimensional shape in a plane. Rewrite this equation in the form $x^2 + ax + b = 0$ and again you should be able to factor the left side and hence solve for $x.$ This will give you two values for $x.$ Substitute these values for $x$ into the factored expression for the area to obtain the dimensions of two possible rectangles. Next, work out the areas of the windows and doors, so they can be subtracted from the full area. You are then told that the area of the rectangle is actually 7 square feet so The combined full area of the front of the house is the sum of the areas of the rectangle and triangle: 66.88 + 9.24 76.12m 2. Learn the methods of calculating the area of a rectangle, facts, solved examples. The Smiths plan to recarpet their family room, which measures 15 ft. The area of a desk top is 8 ¾ square feet. Find the length of a rectangle with area of 16 sq. ![]() However the area of a rectangle is the length times the width so if you can factor $x^2 + 18x + 72$ into two factors then one is the length and the other is the width. If you are measuring the area of a rectangle, then the area will equal the length multiplied by the width. Area of rectangle is given as the product of its length and breadth. Find the area of a rectangle with length of 6 inches and width of 2 feet. You don't know what $x$ represents in this problem but you do know that there is a rectangle which has an area given by $x^2 + 18x + 72$ square feet. if the area of the rectangle is 7 square feet, what are the possible values of x? use factoring to find an expression for the dimensions of the rectangle. The area of a rectangle is given by A=x2+18x+72
