Answer:

[tex] {27.5}^{2} [/tex]

Step-by-step explanation:

[tex]area \: of \: a \: triangle = \frac{1}{2} bh [/tex]

to make the method easy we can divide the fingure into 2 parts

first part

[tex] \frac{1}{2} \times b \times h \\ \\ \frac{1}{2} \times 8 \times 5[/tex]

(because 3+2=5)

[tex] \frac{1}{2} \times 8 \times 5 = {20}^{2} [/tex]

second part

[tex] \frac{1}{2} \times 5 \times 3 = {7.5}^{2} [/tex]

add the 2 areas

[tex] {20}^{2} + {7.5}^{2} = {27.5}^{2} [/tex]
