### Barishal higher secondary 2017#2

A Fibonacci printer is built that always prints equilateral triangle having area of a Fibonacci number but the same height as the equilateral triangle it supposed to print. For example, if it is given to print $3$ square centimeter equilateral triangle, it prints $5$ square centimeter isosceles triangle of the same height. If $5$ square centimeter equilateral triangle in given as input what is the length of the base of the output triangle?
