Dan got a triangle-shaped poster of a yield sign. The base of the poster is 36 inches. The height is 30 inches.

Question

Which equation can you use to find the area of the poster, A?
What is the area of the poster?
square inches

Answer 1

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

\[ A = \frac{1}{2} \times \text{base} \times \text{height} \]

For Dan's triangle-shaped poster, the base is 36 inches and the height is 30 inches. Plugging these values into the formula gives:

\[ A = \frac{1}{2} \times 36 \times 30 \]

Now, calculating further:

\[ A = \frac{1}{2} \times 1080 = 540 \]

So, the area of the poster is:

\[ \boxed{540} \text{ square inches} \]
