### Grade 5 - Mathematics Finding Area/Perimeter of Squares and Rectangles

 Square Area of a square = side x side, A = a x a Perimeter of a square is 4 x side: P = a + a + a + a = 4a Rectangle Area of a rectangle = length x width, A = l x w Perimeter of a rectangle the sum of the lengths of its sides, P = l + w + l + w = 2l + 2w = 2(l + w) Example: Find the area of square of side 4 inches. Area of square = side x side Area = 4 x 4 Answer: 16 square inches Example: Find the perimeter of rectangle whose length is 6 inches and width is 4 inches. Perimeter of rectangle = 2(l+b) Perimeter = 2(6+4) Answer: 20 square inches. Directions: Answer the following questions. Also write at least 10 examples of your own.
