Question

the amount of fencing needed to enclose a backyard is determined by calculating the backyards
to find out how much paint is needed for a room, one must calculate the rooms wall area.
the of water required to fill a swimming pool is calculated using the pools dimensions.
to ensure a ladder reaches the top of a wall safely, the theorem is used to calculate the correct length.
when designing a circular fountain, the is important for specifying the border materials.

Explanation:

• Fencing encloses a space, so perimeter (total length around) is calculated.
• Paint covers surfaces, so wall surface area (area of walls) is calculated.
• Pool volume (space inside) determines water amount.
• Pythagorean Theorem (relates sides of right - triangle) for ladder - wall - ground right - triangle.
• Circular fountain border: circumference (length around circle) for border materials.

Answer:

1. perimeter
2. surface
3. volume
4. Pythagorean
5. circumference
