Area of parallelogram and triangle Review

Front

What is the formula for the area of a parallelogram?

Back

Area = base × height

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 × base × height

Front

What is the height of a parallelogram?

Back

The height is the perpendicular distance from the base to the opposite side.

Front

What is a parallelogram?

Back

A parallelogram is a four-sided figure (quadrilateral) with opposite sides that are parallel and equal in length.

Front

What is a triangle?

Back

A triangle is a three-sided polygon.

Front

How do you find the area of a shaded region in a geometric figure?

Back

Subtract the area of the unshaded part from the total area of the figure.

Front

What is the relationship between the base and height in calculating area?

Back

The area depends on both the base and height; changing either will change the area.

Front

Which figure has a greater area: a triangle or a rhombus with the same base and height?

Back

The rhombus has a greater area because its area is calculated as base × height, while the triangle's area is half of that.

Front

If the base of a parallelogram is 7 cm and the height is 5 cm, what is the area?

Back

Area = 7 cm × 5 cm = 35 cm².

Front

If a triangle has a base of 10 cm and a height of 4 cm, what is its area?

Back

Area = 1/2 × 10 cm × 4 cm = 20 cm².
