Question

1. daves front porch is pictured below. how many square feet of wood will he need to recover the flooring? 8. jessica is thinking of a number. she multiplies number by 3 then subtracts 6. the result is 21. w an equation to represent this problem. use \x\ jessicas original number.

Explanation:

Step1: Calculate the area of the upper rectangle

The upper rectangle has a length of \(3\) feet and a height of \(5\) feet. The area formula for a rectangle is \(A = length\times height\).
\(A_1=3\times5 = 15\) square feet.

Step2: Calculate the area of the lower rectangle

The lower rectangle has a length of \(9\) feet and a height of \(2\) feet. Using the area formula \(A = length\times height\).
\(A_2=9\times2=18\) square feet.

Step3: Sum up the areas

To find the total area of the porch (the amount of wood needed), we add the areas of the two rectangles.
\(A = A_1+A_2\)
\(A=15 + 18=33\) square feet.

Answer:

\(33\) square feet.
