To find the area of a rectangle, multiply the length by the width. 3 x 5 = 15. Do not forget to include the units, however - if the units of the rectangle are in inches, then the answer to the question will be 15 inches squared (15 in2).
To find the area of a square, you square the length of one of its sides. In this case, with a side length of 15 meters, the area would be 15 meters multiplied by 15 meters, which equals 225 square meters. Therefore, the area of a square with a side length of 15 meters is 225 square meters.
