120
Step-by-step explanation:
good luck
Well, a Centimeter is 10 times bigger than a Milimeter.
So we can convert 9cm by multiplying it by 10
9 × 10= 90mm
SInce we know the length and width of the rectangle, we can now find the area of it, or "the space inside".
Area = length × width
Area = 90mm × 81mm
Area = 7290mm
When we have negative exponents, we can move the term with the exponent to the bottom of the fraction. This is also known as multiplying by the reciprocal (and changing the negative exponent to be positive!).
The reciprocal of z^-3 would be 1 / z^3.
Hope this helps!! :)
