Area of Triangles, Rectangles/Squares, Parallelograms Flashcard

Front

What is the formula for the area of a rectangle?

Back

Area = Length x Width

Front

What is the area of a triangle with a base of 10 cm and a height of 5 cm?

Back

Area = 0.5 x Base x Height = 0.5 x 10 cm x 5 cm = 25 cm²

Front

How do you calculate the area of a square?

Back

Area = Side x Side

Front

What is the area of a parallelogram?

Back

Area = Base x Height

Front

If a rectangle has a length of 8 cm and a width of 3 cm, what is its area?

Back

Area = 8 cm x 3 cm = 24 cm²

Front

What is the area of a rectangle with a length of 5 m and a width of 4 m?

Back

Area = 5 m x 4 m = 20 m²

Front

How do you find the area of a trapezoid?

Back

Area = 0.5 x (Base1 + Base2) x Height

Front

What is the area of a square with a side length of 6 in?

Back

Area = 6 in x 6 in = 36 in²

Front

If the area of a rectangle is 30 cm² and the width is 5 cm, what is the length?

Back

Length = Area / Width = 30 cm² / 5 cm = 6 cm

Front

What is the relationship between the area of a rectangle and the area of a square?

Back

A square is a special type of rectangle where all sides are equal, so the area can be calculated using the same formula.
