Use a graphing calculator to solve the nonlinear system. Give x- and y-coordinates to the nearest hundredth.
-Find the dimensions of a rectangular garden with perimeter $62 \mathrm { yd }$ and area $220 \mathrm { yd } ^ { 2 }$.
A) 10 yd by $11 \mathrm { yd }$
B) $10 \mathrm { yd }$ by $22 \mathrm { yd }$
C) 20 yd by 22 yd
D) 20 yd by 11 yd

Question

Quizplus · Accepted Answer

The perimeter equation is $2x + 2y = 62$ and the area equation is $xy = 220$. Solving these equations simultaneously gives the dimensions $x = 20$ and $y = 11$.
