How do you find the area of a square centimeter?
Find the area of a rectangle in square centimeters by measuring the length and width of the rectangle in centimeters. Multiply the length of the rectangle by its width. If the rectangle has a length of 10 cm and a width of 5 cm, the equation is: 10 cm x 5 cm = 50 cm2.
What is the perimeter of a 28cm square?
To find the new perimeter you need to multiply one side of the square by 4. Therefore the perimeter will be 84cm.

| Terms | a = side b=base h=vertical height |
How to calculate the square of a side?
Square Calculations. Calculate q, P, A | Given a. Given the length of a side calculate the diagonal, area and perimeter. q = a√2. A = a 2. P = 4a. Calculate a, P, A | Given q. Given the diagonal length calculate the side length, perimeter and area. a = q / √2.
How to calculate the area of a square room?
Since all sides are equal it does not matter which side is measured. Then simply multiply the measurement by itself to get the area. For example, if the side of a square pool is 10 yards, then the pool area is 10 x 10 = 100 square yards. If one side of a square room is 12 feet, then its area is 12 x 12 = 144 square feet.
