A fence is to enclose a rectangular vegetable farm with an area of 400 square meters. If x is the length of one side of this fence, find a function P(x) representing the perimeter of the fencing materials required. Exercises Exercise 1: Encircle the letter of the correct answer. 1. What is the formula for the area of rectangle? a. A = b. A = lw C. A = 4x d. A = 2(l +w) 2. If x represents one side, how about the other side? a. 400 + x b. 400 - x C. 400x 400 d. 3. What is the formula for the perimeter of rectangle? a. P = - lw b. P = lw d. P = 2(l +w) C. P = 4x 4. Replacing I and w, will lead to P(x) = x(*00) P(x) = x(400 – x) a. b. P(x) = 2(x + (400 – x)) C. 400. d. P(x) = 2(x + 5. Simplifying your answer on number 4. a. P(x) = 400x C. P(x) = 400x – x² P(x) = 800x 2x2+800 b. d. P(x) = litss ond D if Frercigo a
