New House (Solve word problems to find the unknown side given the area of a rectangular shape)

The video tutorial helps John determine the width of a rectangular kitchen floor by using the area formula. Given that the floor can fit 42 one-foot squares and the length is 7 feet, the video guides viewers through calculating the width. By applying the formula for the area of a rectangle (area = length x width), the unknown width is found to be 6 feet. The lesson emphasizes understanding and applying the area formula to solve for missing dimensions in rectangular shapes.

What is the total area of the kitchen floor in square feet?

• 35 square feet

• 49 square feet

• 56 square feet

• 42 square feet

How many one-foot squares can fit in the kitchen floor?

• 35 squares

• 42 squares

• 49 squares

• 56 squares

Which formula is used to calculate the area of a rectangle?

• Area = length / width

• Area = length - width

• Area = length x width

• Area = length + width

If the length of the work area is 7 feet, what is the width if the area is 42 square feet?

• 6 feet

• 8 feet

• 5 feet

• 7 feet

What multiplication fact helps us find the width of the work area?

• 7 x 7 = 49

• 7 x 8 = 56

• 7 x 6 = 42

• 7 x 5 = 35
