<h2><u>Question</u><u>:</u></h2>

<u>Describe</u><u> </u><u>how </u><u>Jason</u><u> </u><u>can</u><u> </u><u>check</u><u> </u><u>his </u><u>answer</u>

<h2><u>Answer</u><u>:</u></h2>

<u>The</u><u> </u><u>e</u><u>q</u><u>uation </u><u>that</u><u> </u><u>w</u><u>as </u><u>given </u><u>in </u><u>the</u><u> </u><u>question</u><u> </u><u>is:</u>

<u>- 8.5 \times  - 3.5 \times  =  - 78</u>

<u>Also,</u><u>the </u><u>value</u><u> </u><u>of </u><u>x</u><u> </u><u>given</u><u> </u><u>is </u><u>6</u><u>.</u><u>5</u><u> </u>

<u>Therefore</u><u>,</u><u> we'll</u><u> </u><u>put </u><u>the</u><u> </u><u>value</u><u> </u><u>of</u><u> x</u><u> </u><u>back </u><u>into</u><u> the</u><u> </u><u>equation </u><u>and </u><u>this </u><u>will </u><u>be:</u>

<u>- 8.5 \times  - 3.5 \times  =  - 78 \\  - 8.5(6.5) - 3.5(6.5) \\  - 55.25 +  - 22.75 \\  =  - 78</u>

<u>Therefore,</u><u> the</u><u> </u><u>answer</u><u> </u><u>is </u><u>correct</u>

Bingel [31]
Knowing that a square gives the optimum area; 

120=s²
√120=s 
√2×2×2×5×3=s
2√2×3×5=s
2√30=s 

Therefore, the length should be ≈10.95" 

Hope I helped :)
