To find the area all you have to do is mulitply the length by the width of the rectangle. So if your rectangle is 6.5 feet long and 2 feet wide: the area is 6.5 ft x 2 ft= 13 ft2. Notice the unit changes from feet (ft) to feet squared (ft2) when you mulitply numbers with...

The area of a square is 144 square feet. How long is each side of the square? A square has side lengths of 3n and n + 18. What is the area of the square? The area of a square is 40 in^2. If the length of each side of the square is 2x in, what is the value of x? Th...
Fortunately, you’re given all the information you need to find the area of the triangle. We are told that the base is 9 and the height is 4 (remember that the height is the line that's perpendicular to the apex, or highest point, of the triangle and the base). Now, just plug th...
