WebStep 1: Find the value of the radius using the formula of the perimeter of the semicircle, P = (πr + 2r), and equate it to the value of the perimeter of the semicircle. Step 2: Once, the equation is obtained, solve for "r". Step 3: Use the formula, A = (πr 2 )/2 to determine the value of the area of the semicircle. WebTo find the perimeter of a rectangle, we use; Perimeter = ( 2 x Length ) + ( 2 x Width ) To find the perimeter of a circle which is also known as the circumference, we use; Circumference = π x Diameter Example: Calculate the perimeter of a rectangular mat whose length is 4m and width 3m. Therefore, the perimeter of the mat is 14m.
