If the perimeter of a rectangular flag is 34 in. and the diagonal is 13 in., then what are the length and width?

Perimeter (P) = 2L + 2w

                34 = 2L + 2w

                17 = L + w

          17 - L = w

L² + w² = d²

L² + (17 - L)² = 13²

L² + 289 - 34L + L² = 169

2L² - 34L + 120 = 0

L² - 17L + 60 = 0

(L - 5)(L - 12) = 0

L - 5 = 0             L - 12 = 0

L = 5                  L = 12

17 - L = w  ⇒ 17 - 5 = 12       or      17 - 12 = 5

width = 5 in, length = 12 in

the answer is 9.8975

explanation:

when you multiply the "39.59" with the 25% it reduces it and shows its final discounted price. hope this !
