Question

The two perpendicular sides of a right angled triangle are in the ratio 3:4 and it’s perimeter is 96 cm. Find the three sides.
​

Answer 1

$\displaystyle\huge\orange{\underline{\underline{Answer}}}$

Let the 2 perpendicular sides be 3x and 4x

therefore by Pythagoras theorem,

hypotenuse = √[(3x)²+(4x)²]

= √[9x²+16x²]

= √25x²

= 5x

perimeter = sum of 3 sides

therefore 96 = 3x+4x+5x

96 = 12x

x = 8

therefore 3x = 24, 4x = 32, 5x = 40

the 3 sides are 24cm, 32cm, 40cm.
