Question

what is the area of $delta wxy$?
area = $square$ square units

Explanation:

Step1: Identify coordinates of vertices

$X(-7, 9)$, $W(10, 9)$, $Y(10, 2)$

Step2: Find base length (XW)

$\text{Length of } XW = |10 - (-7)| = 17$

Step3: Find height (WY)

$\text{Length of } WY = |9 - 2| = 7$

Step4: Calculate triangle area

$\text{Area} = \frac{1}{2} \times \text{base} \times \text{height} = \frac{1}{2} \times 17 \times 7$

Answer:

59.5 square units
