The length of a rectangle can be found using the following formula.



What is the length of a rectangle that has a width of 2.5 centimeters and an area of 20.5 square centimeters?

Respuesta :

Answer:

Length = 8.2 cm

Step-by-step explanation:

A = length * width

length = A / width

length = 20.5 / 2.5

length = 8.2 cm

Check:

A = length*width

A = 8.2 * 2.5

A = 20.5 cm^2

Since area (A), length (l) and width (w) are linked by the formula

[tex]A=lw[/tex]

solving for the length implies (dividing both sides by the width)

[tex]l=\dfrac{A}{w}[/tex]

So, given the area of 20.5 and the width of 2.5, the length is

[tex]l=\dfrac{20.5}{2.5}=8.2[/tex]
