Q. The width of a rectangle measures (3.7f+3.9g) centimeters, and its length measures (3.5f+8.2g) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?7.2f+12.114.4f+24.214.4f+24.2g14.4f+16.4g+3.9
Perimeter Formula: To find the perimeter of a rectangle, we need to add up all the sides of the rectangle. The formula for the perimeter P of a rectangle is P=2×(width+length).
Expressions for Width and Length: First, let's write down the expressions for the width and the length of the rectangle:Width W=(3.7f+3.9g) cmLength L=(3.5f+8.2g) cm
Apply Perimeter Formula: Now, we will apply the formula for the perimeter using the given expressions for width and length:P=2×((3.7f+3.9g)+(3.5f+8.2g))
Combine Like Terms: Next, we combine like terms inside the parentheses:P=2×((3.7f+3.5f)+(3.9g+8.2g))P=2×(7.2f+12.1g)
Multiply by 2: Finally, we multiply each term inside the parentheses by 2 to find the perimeter:P=2×7.2f+2×12.1gP=14.4f+24.2g
