Answer:

98yd²

Explanation:

Alright, for this you'll need the Pythagorean theorem.

${a}^(2) + {b}^(2) = {c}^(2)$

Imagine a right triangle, having twice the given length as the hypotenuse. The legs would be the sides of the square, and therefore be equal.

You can assume it is a square because you're only given half of one diagonal.

Knowing this:

${a}^(2) + {a}^(2) = {14}^(2) \\ 2 {a}^(2) = 196 \\ {a}^(2) = 98$

Therefore, the area is 98 square yards.
