Webb-Area of Parallelograms and Triangles

Front

What is the area of a shape?

Back

The area is the amount of space inside a shape, measured in square units.

Front

What is the area formula for a triangle?

Back

(B x H) ÷ 2, where B is the base and H is the height.

Front

What is the area formula for a parallelogram?

Back

Base x Height, where Base is the length of the base and Height is the perpendicular height.

Front

If the base of a triangle is 8 cm and the height is 5 cm, what is the area?

Back

20 cm² (Area = (8 x 5) ÷ 2).

Front

If the base of a parallelogram is 10 cm and the height is 4 cm, what is the area?

Back

40 cm² (Area = 10 x 4).

Front

What units are used to measure area?

Back

Square units, such as cm², m², or units².

Front

How does the area of a triangle compare to the area of a parallelogram with the same base and height?

Back

The area of the triangle is half the area of the parallelogram.

Front

What is the area of a triangle with a base of 6 units and a height of 3 units?

Back

9 units² (Area = (6 x 3) ÷ 2).

Front

What is the area of a parallelogram with a base of 7 units and a height of 5 units?

Back

35 units² (Area = 7 x 5).

Front

What is the significance of the height in area calculations?

Back

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