Well the difference in the triangle and rectangle prism is that the equation called for 1/2 of the triangles b times h but the rectangle doesn't get divided by two so if the cross sections are equal the for the rectangle it would be v= 50(2)
of v=100
Height of the wall is 27 m.
<u>Explanation:</u>
Let the height of the wall = h
Length of the ladder = 9 m
Angle of elevation = 60°
Ladder rests at 9 m below a vertical wall.
So, length of the wall upto which the ladder rests = h - 9
We know,
Cos Ф = base/ hypotenuse
cos 60° = length of the ladder / height of wall upto which the ladder rests

So,
h - 9 = 18
h = 27
Therefore, height of the wall is 27 m
