Answer:
Triangle R and triangle S are congruent triangles, so finding the area of triangle S would give us the area of triangle R.
The area of a triangle can be calculated as 1/2(bh), where b is the base and h is the height.
In this case, we have: 1/2(5)(4). This simplifies to 10.
So, the area of triangle R is 10 square meters.
