20.25
each side is 4.5
4.5x4.5=20.25
Area of square: 324 square inches Perimeter of square: 72 inches
If the area of the square is 324 square inches then its perimeter is 4*18 = 72 inches
The area of square is : 5184.0
The perimeter is 24cm ******************************** First divide the perimeter by 4, then times the answer by 2, to get the area. Thus: (36 / 4 = 9) x 2 = 18 cm2
17. A 4x4 rectangle has a perimeter of 16 units and an area of 16 square units. A 3x6 rectangle has a perimeter of 18 units and an area of 18 square units. The number 17 is halfway between 16 and 18.
Area of square: 324 square inches Perimeter of square: 72 inches
The square root of 324 is 18 and 4*18 = 72 units of measurement which is the perimeter of the square.
Each side is 72/4 = 18 and its area is 18*18 = 324 square in.
If the area of the square is 324 square inches then its perimeter is 4*18 = 72 inches
The square root of 324 is 18 so the perimeter must be 4*18 = 72 cm
The area of square is : 5184.0
72/4 = 18. Each side of the square is 18, so 18 x 18 = 324. 324 is the area.
The area of the window is 21.8 square feet.
The perimeter is 24cm ******************************** First divide the perimeter by 4, then times the answer by 2, to get the area. Thus: (36 / 4 = 9) x 2 = 18 cm2
A square with an area of 400 square units has a perimeter of 80 units.
17. A 4x4 rectangle has a perimeter of 16 units and an area of 16 square units. A 3x6 rectangle has a perimeter of 18 units and an area of 18 square units. The number 17 is halfway between 16 and 18.
The area and perimeter cannot be equal because the perimeter is a linear measure while an area is a square measure. However, it is perfectly possible for them to have the same numerical value. For example, a 3cm by 6 cm square has a perimeter of 2*(3+6) = 18 cm and an area or 3*6 = 18 sq cm.
