A painter who charges $5 per square meter is tasked with painting the four lateral walls (not the top or bottom) of a rectangular-shaped trailer. Which of the following trailer dimensions would be the costliest to paint?
How would you find the lateral area of the trailer? After all, you want to exclude the top and bottom.
Hi, Is A the answer?
Try it yourself - the problem is at GregMat - GregMat
hey, let me elucidate my doubt. Take “L” as length, “W” as width and “H” as height. you have to exclude the top and bottom of the trailer. My question is which part is the top and bottom? It can either be 2LW(area of both the sides), or 2WH or 2LH. So how do i proceed here
It’s 2(lh + wh). The lw region is the base and roof, which we don’t want.
yeah cleared my doubt, thanks !!
