What is the formula for the area of a trapezoid?

Back

The area of a trapezoid is given by the formula: \( A = \frac{1}{2} (b_1 + b_2) h \), where \( b_1 \) and \( b_2 \) are the lengths of the two bases and \( h \) is the height.

How do you calculate the area of a triangle with a base of 10 ft and a height of 7 ft?

Back

Using the formula \( A = \frac{1}{2} b h \): \( A = \frac{1}{2} \times 10 \times 7 = 35 \text{ ft}^2 \).

What is the area of a trapezoid with bases of 5 yd and 7 yd and a height of 4 yd?

Back

Using the formula \( A = \frac{1}{2} (b_1 + b_2) h \): \( A = \frac{1}{2} (5 + 7) \times 4 = 24 \text{ yd}^2 \).

If the area of a triangle is 20 ft² and the base is 5 ft, what is the height?

Back

Using the formula \( A = \frac{1}{2} b h \): \( 20 = \frac{1}{2} \times 5 \times h \) leads to \( h = 8 \text{ ft} \).
