Area of Triangles, Rectangles, Parallelograms, & Trapezoids

Front

What is the formula for the area of a rectangle?

Back

Area = base × height

Front

What is the formula for the area of a triangle?

Back

Area = (base × height) / 2

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 trapezoid?

Back

Area = (base1 + base2) × height / 2

Front

If a rectangle has a base of 5 meters and a height of 3 meters, what is its area?

Back

Area = 5 m × 3 m = 15 m²

Front

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

Back

Area = (10 cm × 4 cm) / 2 = 20 cm²

Front

What is the area of a parallelogram with a base of 8 inches and a height of 5 inches?

Back

Area = 8 in × 5 in = 40 in²

Front

What is the area of a trapezoid with bases of 6 m and 10 m, and a height of 4 m?

Back

Area = (6 m + 10 m) × 4 m / 2 = 32 m²

Front

Find the area of a rectangle with a length of 12 cm and a width of 7 cm.

Back

Area = 12 cm × 7 cm = 84 cm²

Front

If a trapezoid has an area of 50 square units and a height of 5 units, what is the average of the two bases?

Back

Average of bases = (Area × 2) / height = (50 × 2) / 5 = 20 units
