Question

what is the area of the triangle? 5.5 cm 5 cm 2.5 cm square centimeters submit

Explanation:

Step1: Recall the formula for the area of a triangle

The area of a triangle is given by \( A = \frac{1}{2} \times base \times height \).

Step2: Identify the base and height

From the diagram, the base of the triangle is \( 2.5 \) cm and the corresponding height is \( 5 \) cm (since the dashed line is the height perpendicular to the base).

Step3: Calculate the area

Substitute the values of base and height into the formula:
\( A = \frac{1}{2} \times 2.5 \times 5 \)
First, multiply \( 2.5 \) and \( 5 \): \( 2.5 \times 5 = 12.5 \)
Then, multiply by \( \frac{1}{2} \): \( \frac{1}{2} \times 12.5 = 6.25 \)

Answer:

\( 6.25 \)
