The length is 9 feet and the width is 4 feet.

Step-by-step explanation:

Let the dimensions be L (the length)  and L - 5 (the width).

From the given information the area is:

A = L(L - 5)

When L becomes L + 3 and width becomes (L - 5) -1  = L - 6 we have:

A = (L + 3)(L - 6) so

L(L - 5) = (L + 3)(L - 6)

L^2 - 5L = L^2 - 3L - 18

-2L  = -18

L = 9

so the width = 9 - 5 = 4.

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.
