So first you need to find the area of the building site which is:
length x width
39.5m x 32.5m
= 1283.75
We know that one square meter costs 185.50 euros.
1 = 185.50 euros
1283.75 = <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!
Do 1/2 x 1/10 which equals 10/2. 10/2 is 5 gallons if u divide 10 divided by 2. So the unit rate is 5 gallons per minute. Also can u mark me as brainlist
