The area of square garden is 300m squared. How long is the diagonal?

24.5m

Step-by-step explanation:

I know there is an easier way to do but I am gonna show you a way that I can remember best.

first you want to find the height and base. Of a square, that is isn't to hard since the height is equal the base.

So, squareroot 300.

Which is about 17.3

Now we are gonna do the Pythagorean Theorem.

a^2 + b^2 = c^2

So replace a and b with 17.3

17.3^2 + 17.3^2 = c^2

Okay, so now square 17.3- - Oh look, we already have it.

300 + 300 = c^2

300 + 300 = 600 (Which now we need to squareroot 600 to get our c alone.

Squareroot of 600 = 24.5

So it is 24.5m

The choices for this problem are

a. 5_/6

b. 150

c. 10_/6

d. 900
