Who ever can help me with geometry homework I’ll give brainlist

Step-by-step explanation:

Remark

All of the figures below are rectangles.  They all use the same formula: Area = L * W, so I won't repeat the formula for every part.

Left cross arm

L = 11 mw = 9 mArea = 11 * 9Area =                                                99 m^2

Right Cross Arm

L = 11 mW= 9 mArea = 11 * 9Area =                                                99 m^2

Top

L = 13 mW = 9 mArea =                                               117 m^2

Middle

L=13 mW = 11 mArea =                                               143 m^2

First bottom Closest to the center.

L = 13 mW = 9 mArea =                                               117 m^2

Second Bottom

L= 13 mW = 11 mArea                                                 143 m^2

Total                                                         718 m^2
