PERFORMANCE TASK #4 $Directions$ Read and analyze the situation below. Then answer the questions and $oe\pi om$ the tasks. Association of their barangay, proposed a $po\right)ec$ to put Rudgene Claire, the President of Women's $'$ $sAs$ up a rectangular vegetable garden whose lot perimeter is 40 meters. The said proposal aims to augment the financial needs of each member through sharing and giving free fresh vegetables and fruits during pandemic outbreak. She was soliciting suggestions from her fellow members for possible dimensions of the lot. If you are a member of the club, what will you suggest to $Rudaenθ$ $Clalrθ$ if you want a maximum lot area? You must convince her through a mathematical solution. Consider the following guidelines: 1. Make an illustration of the lot with the $needθ0$ labels. 2. Solve the problem. $Rabm$ for Rating $thcoatpat$ $8co\pi c$ $Dcsciptio$ The $p\pi oblem$ is correctly modelled with a quadratic function, 4 appropriate mathematical concepts are fully used in the solution, and the correct final $an51v0\pi $ is obtained. The $pxoblom$ is $co\pi ectby$ modelled with a quadratic function, 3 appropriate $natbematica$ concepts are partially used in the solution, and the correct final answer is obtained. The $problem$ is not properly modelled with a quadratic function, other 2. alternative mathematical concepts are used in the solution, and the $co\pi 0c$ final answer is obtained. The problem is not totally modelled with a quadratic function; a solution is presented but has incorrect final answer. 4.
