so a rectangle with a^4 times a^9 when multiplying exponents, you just add the exponents because x^4 times x^9 is the same as x x x x times x x x x x x x x*x and you would get a^13 or a to the power of 13
The area of the rectangle is calculated by multiplying the length a 4 yards by the width a 9 yards. Using the property of exponents, the area simplifies to a 13 square yards. Thus, the area of the rectangle is a 13 square yards.
