The bases of a trapezoid measure 1/4 and 3/8 inches, and the height is 1 inch. What is the area of the trapezoid?

Area = average width times the height

A = (5/16) * 1
A = 5/16 square inches

To find the area of a trapezoid, you can use the formula:

Area = (1/2)(a + b)(h)

Where:
- "a" and "b" are the lengths of the trapezoid's bases
- "h" is the height of the trapezoid

In this case, the bases are measured as 1/4 inches and 3/8 inches, and the height is 1 inch.

First, let's convert the base lengths to a common denominator. Since 4 and 8 have a common multiple of 8, we can convert 1/4 to 2/8 and leave 3/8 as it is.

Now, we can substitute the values into the formula:

Area = (1/2)(2/8 + 3/8)(1)

Adding the fractions in the parentheses, we get:

Area = (1/2)(5/8)(1)

Multiplying the fractions and the number, we get:

Area = 5/16 square inches

Therefore, the area of the trapezoid is 5/16 square inches.
