2. A metal bar is 1500 metres long. It is heated and the length increases by 2%. How
long is the bar now?

Let's find 2% of 1500

2%=0,02

1500*0,02=30m

1500+30=1530m

the bar is 1530m long now

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
