The complete question in Spanish is

El área de la región rectangular es 4400 cm2. Calcular el valor de m

largo :2m-20

ancho: m

The question in English is

The area of the rectangular region is 4400 cm2. Calculate the value of m

length :2m-20

width: m

we know that

The area of a rectangle is equal to

where

L is the length

W is the width

we have

substitute in the formula the given values and solve for m

Distribute in the right side

Solve the quadratic equation by graphing

Using a graphing tool

The solution is m=52.17  (the positive value is the solution)

see the attached figure

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'.
