Answer:
See the graphic I made
Area of Section A = 4 *1 = 4 square centimeters
Section B = 4 * (3 + 4) = 28 sq cm
Section C = 3 * (2 + 3 + 4) = 27 sq cm
Total Area = 4 + 28 + 27 = 59 square centimeters
Step-by-step explanation:
Answer:
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)
