Area and Perimeter of Polygons

Front

What is the formula for the area of a trapezoid?

Back

Area = (1/2) * (b1 + b2) * h, where b1 and b2 are the lengths of the two parallel sides and h is the height.

Front

How do you calculate the area of a rectangle?

Back

Area = length * width.

Front

What is the formula for the perimeter of a parallelogram?

Back

Perimeter = 2 * (base + height).

Front

How do you find the perimeter of a triangle?

Back

Perimeter = side1 + side2 + side3.

Front

What is the formula for the area of a triangle?

Back

Area = (1/2) * base * height.

Front

What units are used to measure area?

Back

Square units (e.g., cm², m², etc.).

Front

What units are used to measure perimeter?

Back

Linear units (e.g., cm, m, etc.).

Front

What is the difference between area and perimeter?

Back

Area measures the space inside a shape, while perimeter measures the distance around a shape.

Front

How do you convert cm to m?

Back

To convert cm to m, divide the number of centimeters by 100.

Front

What is the significance of the height in calculating the area of polygons?

Back

The height is the perpendicular distance from the base to the top of the shape, crucial for area calculations.
