Question

what is the area of the trapezoid? 1.3 mm 1.3 mm 0.5 mm 2.5 mm square millimeters

Explanation:

Step1: Recall area formula

The area formula for a trapezoid is $A=\frac{(a + b)h}{2}$, where $a$ and $b$ are the lengths of the parallel - sides and $h$ is the height. Here, $a = 1.3$ mm, $b=2.5$ mm and $h = 0.5$ mm.

Step2: Substitute values

Substitute the values into the formula: $A=\frac{(1.3 + 2.5)\times0.5}{2}$.
First, calculate the sum of the parallel - sides: $1.3+2.5 = 3.8$ mm.
Then, multiply by the height: $3.8\times0.5=1.9$ square mm.
Finally, divide by 2: $A=\frac{1.9}{2}=0.95$ square mm.

Answer:

$0.95$
