P = 2(l+w)
120 = 2(35+w)
120/2 = 35+w
60 = 35 + w
60 -35 = w
25 = w
so width = 25
answer is b. 25 meters
6(1/2 + 2/3 + 3/4)
= 6(1/2) + 6(2/3) + 6(3/4)
= 3 + 4 + 4 1/2
= 11 1/2
Answer
11 1/2 (23/2 or 11.5)
The number of feet in the length of the handrail is 17.3 ft.
The easiest way to see this is to imagine that we can "unfold" the spiral to create a rectangle
The bottom side of the rectangle is just the arc length of a circle with a radius of 3 ft turned through 270°= (3/4) of a whole revolution
(3/4) (2pi) (3) = (9/2)pi ft = 4.5 pi ft
The side of the rectangle will be the rise of the staircase = 10ft
And the diagonal of the rectangle will be the length of the handrail
We can use the Pythagorean Theorem to solve this
Handrail length = √ [ (4.5 pi)^2 + 10^2 ] ≈ 17.3 ft
Pythagorean theorem is the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.
