Answer:
12 cm²
Step-by-step explanation:
Use the area formula A = lw, where l is the length and w is the width:
A = lw
A = (3)(4)
A = 12
= 12 cm²
it must always have one of the sign
30/100
This should be relatively easy since if the denominator is 100 then x/100 has to = 3/10
Since the denominator 10 has to be 100, you multiply by 10.
3 x 10 = 30
