What would the perimeter of a 20ft semicircle be?
That depends on what you mean by a "20 ft semicircle".A semi-circle is a half circle.A 20 ft circle could be:A circle of diameter 20 ftThe perimeter of the semicircle is half the circumference plus the diameter → perimeter = 1/2π 20 ft + 20 ft= 10π + 20 ft≈ 51.42 ftA circle of radius 20 ftThe perimeter of the semicircle is half the circumference plus double the radius → perimeter = 1/2 2π 20 ft + 2 x 20 ft= 20π + 40 ft≈ 102.08 ftA circle of circumference 20 ftThe perimeter of the semicircle is half the circumference plus the diameter → perimeter = 1/2 20 ft + 20 ft ÷ π= 10 ft + 20/π ft≈ 16.37 ftHowever, if a 20 ft circle is a circle with a circumference (= perimeter) of 20 ft then a 20 ft semi-circle could be a semicircle with a perimeter of 20 ft→ perimeter = 20 ft

100
What is the length of a rectangle if the perimeter is 100ft and the width is 20ft?
The perimeter of a rectangle is the sum of all of the sides. That is, length + width + length + width, or 2*length + 2*width. So the total width of the two widths is 20 + 20 = 40ft. By subtracting the total width from the perimeter, we can find the total length. 100 - 40 = 60ft. Because there are two lengths in a rectangle, to find one we must divide by two. 60/2 = 30ft. The length is 30 ft. This problem can also be done algebraically. As an algebraic equation, 2L + 2W = P We know W = 20 and P = 100. 2L + 2*[20] = [100] By multiplication, 2L + 40 = 100 By subtraction, 2L = 100 - 40. 2L = 60 By division, L = 60/2 L = 30ft
How many square feet is 15x20?
300 square feet. To calculate square feet simply multiply length by width - the result is the area in square feet.

Not sure which dimension is which. Normally, the square footage of a room is calculated from its length and width, and not height. However, this question gives depth! Is it a dungeon? Anyway, assuming that the depth is the height, the square footage is 20*15 = 300 sq ft
