Estimate the pressure exerted on a floor by the following.
(a) a 46 kg model standing momentarily on a single spiked heel (area = 0.06 cm2)

Pressure is Force divided by Area
P = F / A
The model has mass 46 kg, so the force she exerts is mg = ( 46 kg ) ( 9.8 m/s^2 ) = 450 N.
The area, .06 cm^2, needs to be converted to square meters.
( .06 cm^2 ) ( .01 m / 1 cm )^2 = .000006 m^2
Now divide the force by the area to get your answer. It will be a very large number!

Are you really saying you can't figure this out? What's the definition of pressure?
