15 + 2xy is the expression represents the charge for the mowing

Step-by-step explanation:

He will charge a mowing fee of $15 plus $2 per square yard of lawn.

Let x be the length of the lawn

y be the width of the lawn

Area of the lawn = length * width

Area = x*y square yards

Given that $2 per square yard

charge of mowing xy square yards = 2xy

Fixed charge is $15 so we add 15 as well

Expression becomes 15 + 2xy
