Step-by-step explanation:

First you have to find the surface are for each shape using its dimensions. Using each shape' surface are you would multiply it with the one with the same dimensions. Then add all of the surface areas together.

A=bh- rectangle with 12ft base and 4 ft height

12·4=48

48·2=96

A=bh- rectangle with 5ft base and 4ft height

5·4=20

20·2=40

A=bh- rectangle with 7ft base and 5ft height

7·5=35

A= bh- triangle with 5ft base and 5ft height

(5)(5)=125

125·4= 50

A=bh- rectangle with 12ft base and 5ft height

12·5=60

A= s²- square with 5ft base and 5ft height

5²=25

96+40+35+50+60+25=306
