Question
Use the method suggested in Exercise 33 to find the area of $\triangle R S T,$ with $R(-2,4), S(-1,-2),$ and $T(6,5)$
Step 1
The rectangle has a length of 8 units (from -2 to 6 on the x-axis) and a width of 7 units (from -2 to 5 on the y-axis). Therefore, the area of the rectangle is $8 \times 7 = 56$ square units. Show more…
