To ensure the proper number amount to the bond make sure that you multiply using the numerator and the denominator as well as check over the passage because you dont know how much to use according to the results so the answers should be
(B)
0. We have 4/6, 36/8, and 12/18
1. Simplify the fractions: 2/3, 9/2, 2/3
2. Order them: 4/6 and 12/18, 36/8
W = L - 5
A = W.L
14 = (L - 5).L
14 = L² - 5L
L² - 5L -14 =0
(L - 7)(L + 2) = 0 {factorized}
L = 7 / L = -2
In this case L would be equal to 7 because a length of anything can't be a negative number
Therefore, W = 2
Answer : Length = 7 Width = 2
