The hypotenuse length of a right angled triangle is 10 cm and the lengths of the two sides of the right angle are x and y cm if it’s perimeter =24 cm find its area

What is the perimeter, p, of a rectangle that has a length of x + 8 and a width of y − 1? p = 2x + 2y + 18 p = 2x + 2y + 14 p = x + y − 9 p = x + y + 7
