Find the area of the figure. Use 3.14 for π.
siniylev [52]

Answer:

Area of the figure= 51.5feet^2

Step-by-step explanation:

Area of the figure=Area of the middle rectangle+ Area the the two triangles

Area of the rectangle=Length*Width

Length= 8+3 =11 feet\\\\Width=4 feet

Area = 11*4\\\\      =44 feet^2

Area of the triangle with the height of 2 feet and base= 3 feet

Area= \frac{1}{2} *Base*Height

==\frac{1}{2} *3*2\\\\=\frac{1}{2}*6\\\\ =3 feet^2

Area of the triangle with the Height=3 feet and Base= 3 feet

Area= \frac{1}{2} *Base*Height

=\frac{1}{2}*3*3\\\\ =\frac{1}{2}*9\\\\ =4.5feet^2

Total Area of the figure=44+3+4.5=51.5 feet^2
