Area of Rectangles and Triangles

Front

What is the formula for the area of a rectangle?

Back

Area = length × width

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 × base × height

Front

If a rectangle has a length of 10 cm and a width of 5 cm, what is its area?

Back

Area = 10 cm × 5 cm = 50 cm²

Front

If a triangle has a base of 8 m and a height of 5 m, what is its area?

Back

Area = 1/2 × 8 m × 5 m = 20 m²

Front

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

Back

Area = side × side = 6 m × 6 m = 36 m²

Front

How do you compare the areas of two shapes?

Back

Calculate the area of each shape and compare the values.

Front

What is the area of a rectangle that is 4 m long and 3 m wide?

Back

Area = 4 m × 3 m = 12 m²

Front

If a triangle has an area of 30 cm² and a base of 10 cm, what is its height?

Back

Height = (Area × 2) / base = (30 cm² × 2) / 10 cm = 6 cm

Front

What is the area of a triangle with a base of 12 cm and a height of 4 cm?

Back

Area = 1/2 × 12 cm × 4 cm = 24 cm²

Front

If two rectangles have the same area, what can we say about their dimensions?

Back

They can have different lengths and widths but their area (length × width) will be equal.
