Question

area of a right triangle is 240 metre square then the hypotenuse is 30 metre find the perimeter ​

Answer 1

answer 30+(2×465^1/2)

let the other sides be x&y

xy/2 =area xy/2 =240 xy=480

x^2+y^2=900 pythagorean theorem

(x+y)^2 =x^2+y^2+2xy

900 + 2×480= 1860

x+y = 1860^1/2

x+y = 2×465^1/2

perimeter = x+y +30

30+(2×465^1/2)

hope this helps
