Answer:
area is equal to 198 cm^2
Step-by-step explanation:
the height h of the left triangle can be obtained by
Pytagoras theorem:
[tex]5^2+h^2=13^2\\25+h^2=169\\h^2=169-25\\h^2=144\\h=\sqrt{144} \\h=12[/tex]
the, the area of the left triangle is
[tex]A_1=\frac{5*12}{2} \\A_1=5*6\\A_1=30[/tex]
the area of the right triangle is
[tex]A_2=\frac{2*12}{2} \\A_2=12[/tex]
and the area of the rectangle in the middle is
[tex]A_3=(13)(12)\\A_3=156[/tex]
Por tanto, el area total sera
[tex]A=A_1+A_2+A_3\\A=30+12+156\\A=198[/tex]
