Perimeter, Area, Coordinate Plane

Front

What is the formula for the area of a rectangle?

Back

Area = length × width

Front

If the area of a rectangle is 36 square meters and the length is 3 meters, what is the width?

Back

Width = Area ÷ Length = 36 ÷ 3 = 12 meters

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 × base × height

Front

What is the definition of perimeter?

Back

Perimeter is the total distance around the outside of a shape.

Front

How do you calculate the perimeter of a rectangle?

Back

Perimeter = 2 × (length + width)

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 × 5 = 25 square units

Front

What is the area of a square with a side length of 4 units?

Back

Area = side × side = 4 × 4 = 16 square units

Front

What is the formula for the area of a circle?

Back

Area = π × radius²

Front

What is the definition of coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a vertical line (y-axis) and a horizontal line (x-axis).

Front

How do you find the area of a composite shape?

Back

Divide the shape into simpler shapes, calculate the area of each, and then sum them up.
