Example LOWER bound

the dimensions COULD be 15.75 (rounds to 15.8) and 5.15 (rounds to 5.2)

lower bound for perimeter could be 2 x (15.75 + 5.15) = 41.8 cm

Of course it is wrong......you didn't do the work did you? I gave you the LOWER limit of perimeter as an EXAMPLE.....you just typed in the answer didn't you?

Lower limit for AREA would be 15.75 x 5.15 = ....... cm^{2}

^{ }

I showed how to obtain the LOWER limit PERIMETER as an EXAMPLE to you ....YOU were supposed to do the UPPER limit of PERIMTER.....

Your Q asks for the LOWER bound of AREA

You need to find the lowerst values that will round to 15.8 and 5.2 which would be 15.75 and 5.15 cm respectively, then:

Lower limit for AREA would be 15.75 x 5.15 = ....... cm2
