By pythagoreans' theorem,

Longer edge
= √(2² + 6²)
= √40

∴ The length of the longer edge is the square root of 40 feet.

Shorter edge
= √(1² + 3²)
= √10

Area = L × B
= √40 × √10
= 20 feet²

1. <span>How long is the longer edge of the table?
</span>AB= \sqrt{(x_b-x_a)^2+(y_b-y_a)^2} = \sqrt{(4-2)^2+(9-3)^2}= \\ = \sqrt{2^2+6^2}= \sqrt{4+36}= \sqrt{40} \  \text{feet}
<span>
2. </span><span>What is the area of the tabletop?
</span>BC= \sqrt{(x_c-x_b)^2+(y_c-y_b)^2} = \sqrt{(7-4)^2+(8-9)^2}= \\ = \sqrt{3^2+(-1)^2}= \sqrt{9+1}= \sqrt{10}  \ \text{feet}  \\  \\ Area=AB*BC= \sqrt{40}* \sqrt{10}= \sqrt{400}=   20 \ \text{square feet}
