Okay so I do Not know what to do this.

I need to draw to Net Scales for the following:

A.) Louvre Pyramid
B = s^2 = 35^2 = 1225 sq. m.
l = ?(20^2 + (17.5^2)) = 26.575m
LA = 4bh = 4(35)(26.575) = 3720.55 sq. m.
SA = B + LA = 1225 + 3720.55 = 4945.55 sq. m
V = (1/3)(1225)(20) = 8166.67 cu. m.

B.) Triangle Bldg.
B = (1/2)bh = (1/2)(20)(20) = 200 sq. m.
LA = Ph
LA = (20 + 20 + 20?2)(25) = 1707.11 sq. m.
SA = 2B + LA
= 2(200) + 1707.11 = 2107.11 sq. m.
V = Bh
= (200)(25) = 5000 cu.m.

If anyone can please help me out I would be truly grateful.

Thanks
