Area Of Polygons 2

Front

What is the formula for finding the area of a kite?

Back

Area = (d1 * d2) / 2, where d1 and d2 are the lengths of the diagonals.

Front

What is the area of a trapezoid?

Back

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

Front

How do you find the area of an irregular shape?

Back

Decompose the shape into simpler shapes, find the area of each, and then sum them up.

Front

What is the area of a rectangle?

Back

Area = length * width.

Front

What is the area of a triangle?

Back

Area = (base * height) / 2.

Front

What is the area of a square?

Back

Area = side * side.

Front

What is the area of a parallelogram?

Back

Area = base * height.

Front

If the diagonals of a kite are 6 units and 4 units, what is its area?

Back

Area = (6 * 4) / 2 = 12 square units.

Front

What is the area of a right trapezoid with bases 5 ft and 3 ft, and height 4 ft?

Back

Area = (1/2) * (5 + 3) * 4 = 16 square feet.

Front

If a trapezoid has an area of 30 square feet and bases of 6 ft and 4 ft, what is its height?

Back

Height = (2 * Area) / (b1 + b2) = (2 * 30) / (6 + 4) = 6 feet.
