Pls help me someone pls can you show your work

If we split this figure into a rectangle and triangle, we can solve:

THe rectangle would have an area of 4.14 (a=b x h) and the triangle would have an area of 8.28 (a=1/2bh)

If we add these numbers together we should have the area

a=4.14+8.28

a=12.42

step-by-step explanation:

see the attached figure to better understand the problem

we know that

a centroid of a triangle is the point where the three medians of the triangle intersect. the centroid divides each median in a ratio of

in this problem the point o is the centroid of the triangle jkl

so

we have

substitute the value
