Question

PLEASEEEE HELP ME!!

The area of a rectangular poster board can be represented by the expression
64x²y. If the width is 16xy, which expression represents the length of the poster
board?
A = length * width

Answer 1

Explanation:

A = length * width

Length = A ÷ width

`= (64x^(2)y)/(16xy)\\\\= 4*x^(2-1)*y^(1-1)\\\\= 4x^(1)*y^(0)\\\\= 4x*1\\=4x`
