To find this, first we have to find the square root of 200, which is about 14.14
Now we multiply 14.14 * 4 = 56.56
So Rae will need about 56.56 feet of fencing to surround the garden.

One of the angle of the triangle is 90 degrees which means it is a right angled triangle. Two angles are same i.e 45 degrees which means the angle is an isosceles triangle.
so, x = 17 (isosceles triangle)
then use pythagoreas theorem:

and x = 17, so simplify and

so

Answer:
35 cuh
