Hello @KatnissMallark :)
you are currently in the Biology section
you would get a better and faster answer if you would ask this in the Mathematics section :)

the Area of a Rectangle = (length) * (width)

but they want the answer in "millimeters" although they gave you the length and stuff in "centimeters"
there are 10 millimeters in 1 centimeter
so to convert centimeter to millimeters you would multiply the given numbers by 10

so width = 8.7cm = 8.7*10 = 87 mm
length = 9.3cm = 9.3 * 10 = 93 mm

area of a rectangle = (87mm) * (93mm) = ?
