Area Calculation of a Right Triangle

Point G is shown on the coordinate plane. Point H is a reflection of point G over the x-axis. What is the y-coordinate of point H?

The distance between two points is 10 units and one of the points is located at (3, -2). What are the other possible points?

A rectangle has vertices at (2, 5), (2, -3), (8, 5), and (8, -3). Maria calculates that the perimeter of the rectangle is 20 units. What is Maria’s mistake?

• Maria correctly calculated the width of 6 units and length of 8 units, but forgot to multiply the sum of the length and width by 2. The perimeter is 28 units.

• Maria made two errors, miscalculating the length and miscalculating the perimeter. The width is 6 units and the length is 8 units. The perimeter is 28 units.

• Maria made two errors, miscalculating the length and miscalculating the perimeter. The width is 6 units and the length is 8 units. The perimeter is 14 units.

• Maria correctly calculated the width of 6 units and length of 8 units, but should have multiplied them to calculate the perimeter of 48 units.

The deck of a boat is shown below. What is the area of the deck in square feet?

The volume of a rectangular prism is 180 cubic feet. Its length is 15 feet. Select all possible options for its height (h) and width (w).

• h = 3 feet, w = 4 feet

• h = 6 feet, w = 2 feet

• h = 5 feet, w = 2 feet

• h = 9 feet, w = 1 foot

• h = 12 feet, w = 1/2 foot
