Perimeter and Area on the Coordinate Plane

What is the relationship between the sides of a right triangle and its area?

• Area (A) = 1/2 × base × height, where base and height are the two shorter sides.

• Area (A) = base × height, where base is the longest side.

• Area (A) = 1/2 × (base + height), where base and height are the two shorter sides.

• Area (A) = base × height × 2, where base is one of the shorter sides.

What is the formula for the area of a trapezoid?

• Area (A) = 1/2 × (base1 + base2) × height.

• Area (A) = base × height

• Area (A) = (base1 + base2) × height

• Area (A) = 1/2 × base × height

How do you find the area of a triangle?

• Area (A) = base × height

• Area (A) = 1/2 × base × height

• Area (A) = base + height

• Area (A) = base × height²

What is the definition of perimeter?

• Perimeter is the total distance around the outside of a shape, calculated by adding the lengths of all its sides.

• Perimeter is the area enclosed by a shape.

• Perimeter is the length of the longest side of a shape.

• Perimeter is the distance from the center of a shape to its edge.

How do you calculate the perimeter of a rectangle?

• Perimeter (P) = 2(length + width).

• Perimeter (P) = length + width.

• Perimeter (P) = 2(length - width).

• Perimeter (P) = length × width.

What is the formula for the area of a square?

• Area (A) = side × side

• Area (A) = 2 × side

• Area (A) = side + side

• Area (A) = side²

What is the formula for the area of a rectangle?

• Area (A) = length × width.

• Area (A) = length + width.

• Area (A) = 2 × (length + width).

• Area (A) = length ÷ width.

How do you round a number to the nearest tenth?

• Look at the hundredths place; if it's 5 or more, round up the tenths place by 1, otherwise keep the tenths place the same.

• Always round down to the nearest whole number.

• Round up if the tenths place is 4 or less, and down if it's 6 or more.

• Ignore the hundredths place and keep the tenths place as is.

What is the significance of vertices in geometry?

• Vertices are the points where two or more lines meet, forming corners of shapes.

• Vertices are the angles formed by intersecting lines.

• Vertices are the lengths of the sides of a shape.

• Vertices are the areas enclosed by shapes.

What is the formula for the area of a circle?

• Area (A) = π × radius²

• Area (A) = 2π × radius

• Area (A) = π × diameter

• Area (A) = radius × height
