Sixty points jose needs to enclose a rectangular section of his yard. the perimeter of the section is 27 feet, and the area is 35 square feet. find the length and width of the section. part i: let l = length of the section and let w = width of the section. the equation for the perimeter is p = 2(l + w). if the perimeter is 27 feet, solve for w. show your work. (1 point) part ii: the equation for area is a = lw. substitute the expression you found for w in part i into the area equation. then, if the area is equal to 35 square feet, write the equation in standard form with a, b, and c as whole numbers. (3 points) part iii: use the quadratic formula, , to solve for l. show your work. (2 points) part iv: use the solution for l in part iii to find the corresponding values for w. show your work. when you're done, state the dimensions of the section.
