Question

A rectangle that has an area of 357 square inches is 17 inches wide. Using the formula for area (A=lw), how long is the rectangle? a. 21 inches b. 340 inches c. 20 inches d. 15 inches

Answer 1

a - 21 inches

Explanation:

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

`357=l*17`

`(357)/(17) =(l*17)/(17) \\\\21=l\\l=21`

Answer 2

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
