Area and perimeter of 2-D shapes problem 156


The area of a right-angled triangle is 25.25 . The length of side b is 6.63 cm, and the perpendicular projection of side a on the hypotenuse c is 5.75 cm. Using the height theorem and both Euclidean theorems, calculate the length of each side of c and the perimeter of the triangle.
