The length of a rectangle is 4 less than three times it's width. The perimeter is 72 feet. Find the dimensions of the rectangle.

Width = 10ft

Length = 26ft

Explanation:

Let width = b,

So, length = 3b-4

Perimeter of rectangle = 2x(length + width)

According to the question,

Hence,

Width = 10ft

Length = 26ft

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.
