Question 127572
How have you tried it so far, what did you do to get $45.00?<br />

I can tell you that $45.00 is most certainly wrong. Let's consider a rectangular desktop 2m across and 1.5m deep. The area of this is 2*1.5=3sq m. The blotter for the rectangular table would therefore cost 3*25=$75, and your table is bigger than this rectange, so your answer must be bigger than $75.<br />

Do you know the formula for the area of a trapezium? Once you know this you should be able to work out the area of the desk. Once you know the area of the desk then the price is just the area times $25.
