25.5 Perimeter and Area on the Coordinate Place

Front

What is the formula for the area of a triangle?

Back

Area of a triangle = 1/2 (base x height)

Front

What is the formula for the area of a rectangle?

Back

Area of a rectangle = length x width

Front

How do you calculate the perimeter of a polygon?

Back

Perimeter = sum of the lengths of all sides

Front

What is the distance formula used to find the length between two points (x1, y1) and (x2, y2)?

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

What is the area of a rectangle with a length of 9 units and a width of 5 units?

Back

Area = 9 x 5 = 45 square units

Front

What is the area of a triangle with a base of 6 units and a height of 4 units?

Back

Area = 1/2 (6 x 4) = 12 square units

Front

Find the perimeter of a triangle with sides measuring 3 units, 4 units, and 5 units.

Back

Perimeter = 3 + 4 + 5 = 12 units

Front

What is the area of a square with a side length of 7 units?

Back

Area = 7 x 7 = 49 square units

Front

How do you find the perimeter of a rectangle with a length of 10 units and a width of 4 units?

Back

Perimeter = 2(length + width) = 2(10 + 4) = 28 units

Front

What is the area of a triangle with a base of 10 units and a height of 5 units?

Back

Area = 1/2 (10 x 5) = 25 square units
