Question

If the difference between the sides of a right angled triangle is 3 cm and its area is 54 cm² ,find its perimeter.

Answer 1

let the sides are x and y.
according to the question, x-y= 3.
& 1/2 * x * y= 54
or x*y= 108
or (y+3)*y= 108
or y^2+3y-108=0

solve this equation and then get x . now u can calculate perimeter.

Answer 2

Answer:

let the sides are x and y.

according to the question, x-y= 3.

& 1/2 * x * y= 54

or x*y= 108

or (y+3)*y= 108

or y^2+3y-108=0
