Please find the surface area in the image attached above

Dear Student
We will use the formula for area of rectangle = length x width

The figure contains following shapes :

2 rectangles of length 4m and width 2m ( one in front and one in back)
Area , A1 = 16
2 rectangles of length 6m and width 2m ( one in front and one in back)
Area , A2 = 24
2 rectangles of length 8m and width 2m ( one in front and one in back)
Area , A3 = 32

6 rectangles of length 7m and width 2m ( 3 in right and 3 in left )
Area ,A4 = 84
4 rectangles of length 2m and width 1m ( 2 in right and 2 in left )
Area , A5 = 8

One rectangle at top of figure of length 4m and width 2m (
Area, A6 = 8

Adding all areas
Total area = 172 m²

Thanks
