Answer:
soccer field is your answer
Given:
trap door = 130 square feet.
1st item: 6ft 5in wide & 8ft 9in long
⇒ (6ft * 12 in) + 5 in & (8ft *12 in) + 9 in
⇒ 77inches by 105 inches
⇒ 8,085 square inches
2nd item: 13ft 4in wide & 7ft 8in long
⇒ (13ft * 12in)+ 4 in & (7ft *12in) + 8 in
⇒ 160 inches by 92 inches
⇒ 14,720 square inches
3rd item: 5ft 6in wide & 12ft 4in long
⇒ (5 ft * 12in) + 6 in & (12ft * 12in) + 4in
⇒ 66 inches by 148 inches
⇒ 9,768 square inches
130 square feet convert to square inches.
130 sq. ft * 144 sq.in/sq.ft = 18,720 sq. in
18,720 sq. in / 160 inches = 117 inches
Length = 160 inches ; Width = 117 inches
Perimeter = 2(160 + 117)
P = 2(277)
P = 554 inches
You can find all of this in one step using synthetic division. If one root is x = 12.5, that means when we use 12.5 in our synthetic division we will have a remainder of 0. Put 12.5 outside the "box" and the leading coefficients of our polynomial inside like this: 12.5 (1 -13 q). Bring down the first 1. Multiply it by the 12.5 to get 12.5. Put that 12.5 up under the -13 and add to get -.5. Multiply that -.5 by the 12.5 to get -6.25. Put that -6.25 up under the q. Since we need this addition to equal 0, q has to be 6.25. That is the coefficient that will take the place of q. What we have left are the bolded numbers that represent the depressed polynomial that is one degree less than the polynomial we started with. It has an equation of x - .5 = 0. We solve this for x to get the other root of the polynomial. x = .5. And there you go!
