A 34-ft. ladder resting against the wall of a building forms a right triangle with the wall and ground. The bottom of the ladder
is 8 ft. away from the base of the building. How far up the side of the building does this ladder reach?

A 34-ft. ladder resting against the wall of a building forms a right triangle with the wall and ground. So this is one of the legs and equal 34 feet.
The bottom of the ladder is 8 ft. away from the base of the building. This is another leg and equal 8 feet.
You need to find the hypotenuse.
Using The Pythagorean Theorem:
c^2 = a^2 + b^2, where a and b are legs and c is hypotenuse
c^2 = 34^2 + 8^2
c^2 = 1156 + 64
c^2 = 1220
c = √1220
c = 34.93
Answer
The side of the building = 34.93 ft
Answer: 26 feet

Length will be represented as l and breadth as b.
perimeter=l+l+b+b=45+45+b+b=150
b+b=150-45-45=60
b=60÷2=30
area=lxb=45x30=135
the area is 135 feet.
The area of a parallelogram is base X height.
so here will be 20 x h = 300
therefore the height is 15
