Question

the area of right angled triangle is 84 square metre if the base is 24 cm and the hypotenuse is 25 cm find its perimeter ​

Answer 1

Answer:

56cm

Step-by-step explanation:

area = 84 cm²

base = 24cm²

hypotenuse = 25 cm²

let last side be x

x² + 24² = 25²

x² + 576 = 625

x² =625 - 576

x² = 49

x = √49

x = 7

therefore. sides are 7cm , 24cm , 25cm

therefore. perimeter = 25 + 24 + 7

perimeter = 56cm
