Answer:

B. 7.5 square units.

Explanation:

We have been given an image of a right triangle. We are asked to find area of our given triangle.

We can see that base of our given triangle is 5 units as difference between point S and point T is 5 units.

2--3=2+3=5

The height of our given triangle (RT) is 3 units.

1--2=1+2=3

$\text{Area of triangle}=(1)/(2)* \text{Base}* \text{Height}$

$\text{Area of triangle}=(1)/(2)* \text{5 units}* \text{3 units}$

$\text{Area of triangle}=(1)/(2)* 15\text{ units}^2$

$\text{Area of triangle}=7.5\text{ units}^2$

Therefore, area of our given triangle is 7.5 square units and option B is the correct choice.
