Question

if the length of the sides of a right angled triangle are x-6, x+8 and x+10cm. and the area of this triangle is 120 cm^2 then find the perimeter of this triangle

Answer 1

x2+(x−1)2=(x+1)2x2+(x−1)2=(x+1)2

⟹2x2–2x+1=x2+2x+1⟹2x2–2x+1=x2+2x+1

⟹x2–4x=0⟹x2–4x=0

⟹x(x−4)=0⟹x(x−4)=0

⟹x=4

Answer 2
