Question

I need help on number 9, picture is included!

Answer 1

ok unit conversions

you know that 12 inches are in a foot
and 100 centimeters are in 1 meter

so starting with a)
you start with 2 ft^2


`2 ft^2 = \frac{2 ft^2}{} * (12 in)/(1 ft) = 24 ft\ in = \frac{2 ft \ in }{} * (12 in)/(1 ft) = 288 in^2`
