Perimeter is the measurement of the distance around the outside of a shape. It is the total length of all the sides of the shape. For example, if you have a square with sides of 4 inches each, the perimeter would be 4 + 4 + 4 + 4 = 16 inches.The formula for finding the perimeter of different shapes is as follows:1. For squares and rectangles: Perimeter = 2 * (length + width) 2. For triangles: Perimeter = side1 + side2 + side3 3. For circles: Perimeter = 2 * π * radiusIt's important to note that the units for perimeter will be the same as the units used to measure the sides of the shape. For example, if the sides are measured in inches, the perimeter will be in inches as well.Understanding perimeter is important for young students as it helps them develop spatial awareness and a basic understanding of geometric principles. It also lays the groundwork for more advanced concepts in geometry as students progress through their education..
