Luka's Pool (Calculate the area of a specific portion of a figure)

Luka needs to calculate the area of his pool deck excluding the pool to buy the correct amount of stain. The deck's dimensions are 26 feet by 18 feet, and the pool's dimensions are 20 feet by 12 feet. By calculating the total area of the deck and pool together and then subtracting the pool's area, Luka finds the deck's area to be 228 square feet. This lesson demonstrates how to calculate the area of a specific portion of a figure.

What is the first step Luka needs to take to find the area of the deck without the pool?

• Calculate the area of the pool only

• Calculate the area of the deck including the pool

• Measure the perimeter of the deck

• Estimate the area visually

How does Luka calculate the area of the deck including the pool?

• By adding the length and width

• By multiplying the length and width

• By subtracting the pool area from the deck area

• By dividing the length by the width

What is the area of the pool alone?

• 312 square feet

• 468 square feet

• 240 square feet

• 228 square feet

What is the final area of the deck that Luka needs to stain?

• 228 square feet

• 468 square feet

• 300 square feet

• 240 square feet

Why does Luka subtract the pool area from the total deck area?

• To find the perimeter of the deck

• To determine the amount of stain needed

• To calculate the area of the pool

• To find the area of the deck without the pool
