Find.the.area. perimeter.of square pqrs if one side is equal (1)20cm
To find the area and perimeter of a square, you need to know the length of one of its sides. In this case, the length of one side is 20 cm.
To find the area of a square, you need to square the length of one side. So, in this case, the area would be (20 cm) * (20 cm), which equals 400 square cm.
To find the perimeter of a square, you need to add up the lengths of all four sides. Since all sides of a square are equal, you can simply multiply the length of one side by 4. So, in this case, the perimeter would be 20 cm * 4, which equals 80 cm.
Therefore, the area of square PQRS is 400 square cm and the perimeter is 80 cm.
