How do you Find the Area of a Rectangle How do you Find the Area of a Rectangle The area of a polygon is the number of square units inside the polygon. To understand the difference between perimeter and area, think of perimeter as the length of fence needed to enclose the yard, whereas area is the space inside the yard. Perimeter is 1-dimensional and is measured in linear units such as inches, feet or meters. Area is 2-dimensional: it has a length and a width. Area is measured in square units such as square inches, square feet or square meters. Area is measured in "square" units. The area of a figure is the number of squares required to cover it completely, like tiles on a floor. Area of a square = side times side. Since each side of a square is the same, it can simply be the length of one side squared. If a square has one side of 4 inches, the area would be 4 inches times 4 inches, or 16 square inches. (Square inches can also be written in2.) Be sure to use the same units for all measurements. You cannot multiply feet times inches, it doesn't make a square measurement.

The area of a rectangle is the length on the side times the width. If the width is 4 inches and the length is 6 feet, what is the area? Example 1: Find the area of the garden, length and width of the garden is 600m and 400m? Solution: Area of the garden = l x b = 600 x 400 = 240000 m2 Example 2: Find perimeter and area of a rectangle whose length is 4cm and breadth is 7cm Solution: Formula for area of rectangle = l Ă— b =4Ă—7 = 28cm2 Perimeter of the rectangle = 2L +2W = 2(4) + 2(7) = 8 + 14 = 22cm.
