The area of a rectangular field is 6840 m2. If the width of the field is 72m , what is its length?
IgorLugansk [536]

Answer:

I believe that the answer is 95 meters.

Explanation:

Okay, so to solve this question, you must know the formula to solve for the area of a rectangle/square.

<em>Area of a rectangle/square - </em><em>l x w</em>

<em />

In this question, you can see the the width (72 m) and the area (6840 m²) is already given. What you can do in this situation is to use the opposite operator (division) to solve for the length of the rectangular field.

<em>6840 ÷ 72 = </em><em>95</em>

You can always double check to see if the number is correct.

<em>A = l x w</em>

<em>= 72 m x 95 m</em>

<em>= </em><em>6840 m</em>²

Really hope this helped. :)

Write an equation for each problem. Then solve.
Nana76 [90]

Answer:

<em>The price is the same at both stores for 2 prints.</em>

Step-by-step explanation:

<u>Equations</u>

Let's set the variable

x = number of photo prints

Company Photo Plus charges $2 for each print and $6 for a processing fee, thus the total charges are:

PP = 6 + 2x

Company Picture Time charges $3 for each print and $4 for a processing fee, thus it charges a total of:

PT = 4 + 3x

It's required to find the number of prints that make both stores charge the same. Equating both functions:

6 + 2x = 4 + 3x

Subtracting 2x and 4:

x = 2

The price is the same at both stores for 2 prints.
