Question

A rectangular fountain has an area of (4x^(2)+12x+9)ft^(2). the dimensions of the whole fountain are of the form cx+d, where c and d are whole numbers. Find an expression for the perimeter of the fountain. Find the perimeter when x=2ft.

Answer 1

The ^(2) represents squared.

Answer 2

Any answers?

Answer 3

4x²+12x+9 = 0
(2x + 3 )²
Thus dimension ( 2x +3) ( 2x +3)
