The length of a rectangle is 3 inches. Enter an expression for the area of the rectangle if the width is w inches. Find the area of the rectangle when the width is 1, 2 , 3, and 26 inches

An expression for the area of the rectangle if the width is w inches is

3w

when the width is 1 inch, Area = 3 square inches (in²)

when the width is 2 inches, Area = 6 square inches (in²)

when the width is 3 inches, Area = 9 square inches (in²)

when the width is 26 inches, Area = 78 square inches (in²)

Step-by-step explanation:

The area of a rectangle is given by

×

Where is the area of the rectangle

is the length of the rectangle

and is the width of the rectangle

From the question,

length, = 3 inches

width, = w inches

Hence, An expression for the area of the rectangle is

3 × w

3w

Now, to find the area of the rectangle when the width is 1, 2 , 3, and 26 inches

1. when the width is 1 inch (That is  = 1 inch)

Then, 3w

3 × 1

3 square inches (in²)

2. when the width is 2 inches (That is  = 2 inches)

Then, 3w

3 × 2

6 square inches (in²)

3. when the width is 3 inches (That is  = 3 inches)

Then, 3w

3 × 3

9 square inches (in²)

4. when the width is 26 inches (That is  = 26 inches)

Then, 3w

3 × 26

78 square inches (in²)
