We can obtain acute angle triangle and scalene triangle.
We can obtain acute angle triangle and scalene triangle.
Given height of a room be x,
Let length of room be l and breadth be b, respectively, then,
bh = y and lh = z
⇒ bx = y and lx = z
∴ b = y/x and l = z/x
So, area of roof = l = b = (z/x) × y/x
= yz/x2
