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!
Rearranging the first equation we get that b^2 = 1-a^2
Substituting this is to the second equation we get
Root 9(b^2)(b^2) or
Root 9(b^2)^2
this simplifies to 3b^2
The only thing you need to solve this task is to know the p<span>ercent error formula:
</span> (theoretical value-experimental value): theoretical value)) * 100
Your theoretical value is 279, as it is the value that you know<span>, and the experimental -250 is your calculated value.
</span>279-250/279
29/250
0.116*100
11.6%
Then you can recheck everything:
250*0.116=29
<span>250+29=279</span><span>
</span>
