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

What is the formula for the area of a triangle?

Back

The area of a triangle is calculated using the formula: Area = (base × height) / 2.

Front

How do you find the area of a square?

Back

The area of a square is calculated using the formula: Area = side × side.

Front

What is the area of a rectangle with a length of 8 feet and a width of 4 feet?

Back

Area = 8 ft × 4 ft = 32 ft².

Front

If a triangle has an area of 160 square inches and a base of 40 inches, how do you find the height?

Back

Use the formula: Area = (base × height) / 2. Rearranging gives height = (Area × 2) / base. So, height = (160 in² × 2) / 40 in = 8 in.

Front

What is the area of a figure with a length of 12 inches and a width of 4 inches?

Back

Area = 12 in × 4 in = 48 in².

Front

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

Back

Area = (10 in × 5 in) / 2 = 25 in².

Front

How do you calculate the area of a parallelogram?

Back

The area of a parallelogram is calculated using the formula: Area = base × height.

Front

What is the area of a rectangle with dimensions 6 inches by 10 inches?

Back

Area = 6 in × 10 in = 60 in².

Front

If a rectangle has an area of 48 square inches and a width of 6 inches, what is the length?

Back

Length = Area / width = 48 in² / 6 in = 8 in.
