What is the perimeter of square efgh, shown?

a. 14.1
b. 28.3
c. 34.5
d. 17.3

B. 28.3

Step-by-step explanation:

Because this is a square, you just need to find the length of one side.

Let us pick one side:

Line EF

The coordinates of the two points of Line EF are (0,5) and (5,0)

The distance formula between two points is:

So we just fill in the formula and solve:

Now that we have that, we just multiply it by 4.

7.07 units x 4 = 28.28 units or 28.3 units

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
