Ответ:
if you loo at the photo you will see
so if 676 = s^2
√676 = s
26 = s
ans = one side of the square is 26 yards

So there is no way to properly square root a number unless you memorize it. However, what you can do, is look at the last digit and make an approximation, at which two numbers multiply together to have a last digit of 6.
So, 4 * 4 and 6 * 6 are the two that square to have a last digit of 6.
(1: 1, 2: 4, 3: 9, 4: 6, 5: 5, 6: 6, 7: 9, 8: 4, 9: 1, 0: 0) If that makes any sense.
So basically the square root has to end with 4 or 6.
Now, you can just approximate. It would be over 20, because 20 squared (20 * 20) is equal to 400. But it would be under 30, because 30 squared is 900.
So the two possible numbers are 24 and 26.
If you square both of them, you find that:
24 squared = 576
26 squared = 676
So therefore 26 is the square root of 676, so therefore one side is 26 yards.
Hope this weirdly long explanation helped :)

In the image attached you can find the Unit 7 homework.
We need to findt he missing measures of each figure.
1.Notice that the first figure is a rectangle, which means opposite sides are congruent so,
VY = 19
WX = 19
YX = 31
VW = 31
To find the diagonals we need to use Pythagorean's Theorem, where the diagonals are hypothenuses.
Also,
, beacuse rectangles have congruent diagonals, which intercect equally.
That means,![ZX = \frac{VX}{2} \approx \frac{36.36}{2}\approx 18.18](/tpl/images/0628/2090/c8502.png)
2.Figure number two is also a rectangle.
If GH = 14, that means diagonal GE = 28, because diagonals intersect in equal parts.
Now, GF = 11, because rectangles have opposite sides congruent.
DF = 28, because in a reactangle, diagonals are congruent.
HF = 14, because its half of a diagonal.
To find side DG, we need to use Pythagorean's Theorem, where GE is hypothenuse
![GE ^{2}=11^{2}+DG^{2}\\28^{2}-11^{2}=DG^{2}\\DG=\sqrt{784-121}=\sqrt{663}\\ DG \approx 25.75](/tpl/images/0628/2090/e9689.png)
3.This figure is also a rectangle, which means all four interior angles are right, that is, equal to 90°, which means angle 11 and the 59° angle are complementary, so
Now, angles 11 and 4 are alternate interior angles which are congruent, because a rectangle has opposite congruent and parallel sides.
Which means
, beacuse it's the complement for angle 4.
Now,
, because it's a base angle of a isosceles triangle. Remember that in a rectangle, diagonals are congruent, and they intersect equally, which creates isosceles triangles.
, by complementary angles.
4.
, by supplementary angles.
5.
, by alternate interior angles.
6.The figure is a rectangle, which means its opposite sides are equal, so
Then, we replace this value in the expression of side WZ
Therefore, side WZ is 29 units long.
7.We know that the diagonals of a rectangle are congruent, so
Then,
Therefore, side PR is 73 units long.
