Answer:
7 Units^2
Step-by-step explanation:
If we add an exact copy of the triangle, we can make a parallelogram.
Then we can use the parallelogram's area to figure out the triangle's area.
Hint #22 / 4
The original triangle has \dfrac{1}{2}
2
1
start fraction, 1, divided by, 2, end fraction the area of the parallelogram we just made.
Hint #33 / 4
\begin{aligned} \text{Area of parallelogram} &= \text{base} \times \text{height}\\\\ \text{Area of triangle} &= \dfrac{1}{2} \times \text{base} \times \text{height}\\\\ &= \dfrac{1}{2} \times 7 \times 2\\\\ &= \dfrac{1}{2} \times 2 \times 7\\\\ &= 1 \times 7\\\\ &= 7 \end{aligned}
