(See attached files for full problem description) For this one you need chapter 2 I think, it is problem number 4 page 57.

Word problem

(See attached file for full problem description) The area A of an equilateral triangle varies directly as the square of the length of a side. If the area of the equilateral triangle whose sides are of length 2 cm is (√3) cm2 , find the length s of an equilateral triangle whose area A is (√3)/4 cm2.
