Area of a Triangle

Front

What is the formula for the area of a triangle?

Back

A = \frac{1}{2} bh, where A is the area, b is the base, and h is the height.

Front

What does 'b' represent in the area formula A = \frac{1}{2} bh?

Back

'b' represents the length of the base of the triangle.

Front

What does 'h' represent in the area formula A = \frac{1}{2} bh?

Back

'h' represents the height of the triangle, measured perpendicular to the base.

Front

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

Back

A = \frac{1}{2} \times 10 \times 5 = 25 \ cm^2.

Front

If the area of a triangle is 30 m^2 and the base is 10 m, what is the height?

Back

Using A = \frac{1}{2} bh, we have 30 = \frac{1}{2} \times 10 \times h. Thus, h = 6 m.

Front

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

Back

A = \frac{1}{2} \times 8 \times 4 = 16 \ in^2.

Front

If a triangle has an area of 50 yd^2 and a height of 5 yd, what is the base?

Back

Using A = \frac{1}{2} bh, we have 50 = \frac{1}{2} \times b \times 5. Thus, b = 20 yd.

Front

What is the area of a triangle with a base of 12 ft and a height of 3 ft?

Back

A = \frac{1}{2} \times 12 \times 3 = 18 \ ft^2.

Front

What is the area of a triangle with a base of 14 cm and a height of 7 cm?

Back

A = \frac{1}{2} \times 14 \times 7 = 49 \ cm^2.

Front

What is the area of a triangle with a base of 6 m and a height of 10 m?

Back

A = \frac{1}{2} \times 6 \times 10 = 30 \ m^2.
