Question

I am having difficulty solving this problem

Answer 1

`\bf \textit{area of this square}\\\\ A=s^2\qquad \boxed{s=42}\implies A=42^2\implies A=\stackrel{inches}{1764}\\\\ -------------------------------\\\\ \textit{area for this rectangle}\\\\ A=lw\quad \begin{cases} w=26\\ l=73(2)/(3)\\\\ \qquad (73\cdot 3+2)/(3)\\\\ \qquad (221)/(3) \end{cases}\implies A=\cfrac{221}{3}\cdot 26\implies A=\cfrac{5746}{3} \\\\\\ A=\stackrel{inches}{1915(1)/(3)}\\\\ -------------------------------\\\\`


`\bf \textit{area for this circle}\\\\ A=\pi r^2\quad \begin{cases} diameter=36\\ r=radius=(diameter)/(2)\\ r=18 \end{cases}\implies A=\pi 18^2\implies A=324\pi \\\\\\ A\approx \stackrel{inches}{1017.876019763}`
