Answer: A=72x5
Explanation:
The formula for the area of a rectangle is:
Area=length*width
here,
length=12x3
width=6x2
Putting these values in the formula for area gives-
Area= 12x3*6x2
simplifying the equation gives-
Area = (12*6)*(x3*x2)
we can multiply the constants and use the exponents rule to multiply the terms with power.
y^a* y^b = y^(a+b)
that provides us with-
Area = 72 *(x^(3+2))
Area = 72x5
