what is the approximate area of the coin?
a. 34.54mm to the power of 2
b. 69.08mm to the power of 2
c. 94.99mm to the power of 2
d. 379.94mm to the power of 2

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'.
