expres total area of field, end zones in terms of w

[igor_iv837]

An athletic field has dimensions 30 yd by 100 yd. An end zone that is w yards wide borders each end of the field. Express the total area of the field and the end zones in terms of the variable w.

area is BASE * TIMES
100*30 and 2 sides times 30
answer is (3000+60w) yd^2
is it right?

That's what I get assuming the end zone spans the entire width of the field (30 yd).
