Question

what is the area of the triangle? 1 mm 2 mm square millimeter

Explanation:

Step1: Recall area formula

The formula for the area of a triangle is $A=\frac{1}{2}bh$, where $b$ is the base and $h$ is the height.

Step2: Identify base and height

From the image, the base $b = 1$ mm and the height $h=2$ mm.

Step3: Substitute values

Substitute $b = 1$ mm and $h = 2$ mm into the formula: $A=\frac{1}{2}\times1\times2$.

Step4: Calculate area

$A = 1$ square - millimeter.

Answer:

1 square millimeter
