El área de la región rectangular es 4400cm2. Calcula el valor de m
Roman55 [17]

Answer:

m=52.17

Step-by-step explanation:

<em>The complete question in Spanish is</em>

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

largo :2m-20

ancho: m

<em>The question in English is</em>

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

A=LW

where

L is the length

W is the width

we have

A=4,400\ cm^2

L=(2m-20)\ cm

W=m\ cm

substitute in the formula the given values and solve for m

4,400=(2m-20)m

Distribute in the right side

4,400=2m^2-20m

2m^2-20m-4,400=0

Solve the quadratic equation by graphing

Using a graphing tool

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