A = L * W
A = 357
W = 17

357 = 17L
357 / 17 = L
21 = L <== length is 21 inches

Answer:

<em>The correct option is: a. 21 inches</em>

Step-by-step explanation:

The area of the rectangle is 357 square inches and width is 17 inches.

<u>Formula for the area of rectangle is</u>: $Area= Length\times Width$

Suppose, the length of the rectangle $=x$ inches.

So, the equation will be.....

$357=x\times 17\\ \\ \frac{357}{17}=\frac{x\times 17}{17}\ [Dividing\ both\ sides\ by\ 17]\\ \\ 21=x$

So, the rectangle is 21 inches long.
