The formula of an area of a square:


A=a^2


a - a side


We have A=450\ in^2


substitute:


a^2=450\to a=\sqrt{450}\\\\a=\sqrt{225\cdot2}\\\\a=\sqrt{225}\cdot\sqrt2\\\\\boxed{a=15\sqrt2\ in}


Used:

\sqrt{a\cdot b}=\sqrt{a}\cdot\sqrt{b}

Marizza181 [45]
Hi there! An equation for this problem would look something like

12d=75

Since the farmer can harvest 12 acres per day, the variable d represents days. 12 times the number of days it would take to harvest the field would equal 75.
