Answer:
Step-by-step explanation:
Tex wants to make a lawn in the front of his house. The total yards are 30 by 30 yards. This means that the total area of the lawn is
30 × 30 = 900 yards^2
he gets 20 by 10 yards. This means that the total area of what he got would be
20 × 10 = 200 yards^2
Since what he needs is 900 yards^2 and it is greater than what he got, 200 yards^2, then it won't be enough.
What he needs more would be
900 - 200 = 700 yards^2
