ein rechteckiger Bauplatz ist 39,5 m lang und 32,5 m breit . wie teuer ist der Grund ,wenn ein Quadratmeter Bauland 185,50 euro

Setler79 [48]

So first you need to find the area of the building site which is:

length x width

39.5m x 32.5m

= 1283.75 $m^{2}$

We know that one square meter costs 185.50 euros.

1 $m^{2}$ = 185.50 euros

1283.75 $m^{2}$ = <u>238135.625 euros</u>

I'm not exactly that familiar with euros but I'm pretty sure that euros don't have 3 numbers after the point so the two nearest numbers are <u>238134.86 and 238135.86.</u>

sorry if this is wrong, but I hope it helps, if the euros part is wrong please correct me thanks!
