Answer:
1.If a triangle has all three sides of different lengths, it is a scalene triangle. The perimeter of a scalene triangle can be calculated by finding the sum of all the unequal sides. The formula for the perimeter of a scalene triangle is: Perimeter = a + b + c, where "a", "b", and "c" are the three different sides.
2.In order to calculate the perimeter of the square, we will find the sum of all of its sides. Since, all the sides of a square are equal, for a square, with each side measuring "s" units, perimeter will thus be given as, Perimeter of square = s + s + s + s.
3.To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results
4.The formula for the area of a square when the sides are given, is: Area of a square = Side × Side = S2. Algebraically, the area of a square can be found by squaring the number representing the measure of the side of the square
5.A = l × b. The area of any rectangle is calculated, once its length and width are known. By multiplying length and breadth, the rectangle's area will obtain in a square-units dimension.
