Area of Rectangles and Triangles

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is calculated using the formula: Area = length × width.

Front

Calculate the area of a rectangle with a length of 6 cm and a width of 4 cm.

Back

Area = 6 cm × 4 cm = 24 cm².

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is calculated using the formula: Area = \frac{1}{2} × base × height.

Front

Calculate the area of a triangle with a base of 10 ft and a height of 5 ft.

Back

Area = \frac{1}{2} × 10 ft × 5 ft = 25 ft².

Front

If a rectangle has an area of 42 yd² and a width of 6 yd, what is its length?

Back

Length = Area ÷ Width = 42 yd² ÷ 6 yd = 7 yd.

Front

What is the area of a triangle with a base of 8 cm and a height of 4 cm?

Back

Area = \frac{1}{2} × 8 cm × 4 cm = 16 cm².

Front

How do you convert square centimeters to square meters?

Back

To convert square centimeters to square meters, divide by 10,000 (1 m² = 10,000 cm²).

Front

What is the area of a rectangle with a length of 5 m and a width of 3 m?

Back

Area = 5 m × 3 m = 15 m².

Front

If the area of a triangle is 50 ft² and the base is 10 ft, what is the height?

Back

Height = (Area × 2) ÷ Base = (50 ft² × 2) ÷ 10 ft = 10 ft.

Front

What is the relationship between the area of a rectangle and the area of a triangle with the same base and height?

Back

The area of the triangle is half the area of the rectangle: Area of triangle = \frac{1}{2} × Area of rectangle.
