You do not have a complete question. I do not know the dimensions of the half pipe nor the deck. I will assign letters to these. Hopefully that will help.
R = radius of the pipe
L = length of the pipe
W = width of deck
l = length of deck
area of the half pipe is the circumference of the pipe times its length.
Area-half-pipe = pi * R * L
Area of the deck = W * l
If the two decks have the same dimensions then double this number and add them up.
If the half-pipe has a flat cover its area is 2*R*L
Both a rhombus and a rectangle have diagonals that are perpendicular bisectors, but the ones formed in a square are all congruent, so that is probably the most descriptive one.
Ok so u know to divide bc u r trying to isolate the variable and that means undoing the function in this case 0.6 is multiplied to p so u do the opposite which is division
