Respuesta :

Answer: a. 21 inches 
The rectangle that has an area of 357 square inches(a=357) is 17 inches wide(w=17). You are asked how long the length of the rectangle is. Then, you just need to put the number into the equation provided.

a=lw
area= length * width
357=length * 17
length= 357/17=21 inches

Answer:

a - 21 inches

Step-by-step explanation:

Following the formula [tex]Area = l*w[/tex], we can find the length of the rectangle by plugging in values into the formula, then solving for [tex]l[/tex].

[tex]357=l*17[/tex]

[tex]\frac{357}{17} =\frac{l*17}{17} \\\\21=l\\l=21[/tex]
