Answer:
89 square cm
Step-by-step explanation:
The shape has two rectangles and two triangles. The triangles are at the edges and for the area for triangle we get by 0.bh where b is base and h is heigjt. Since the triangles are same then the above formula is multiplied by 2 hence area is 0.5bh*2=bh. Here b is 4cm and h is 3 cm then are is [tex]4*3=12 cm^{2}[/tex]
Area of rectangle is given by lw where l is length and w is width
For the rectangle at the bottom, the area is [tex]11*4=44 cm^{2}[/tex]
For the rectangle on side, the area is [tex]11*3=33 cm^{2}[/tex]
Total area is 12+44+33=89 square cm
