Answer:
D) 27
Step-by-step explanation:
It's a rectangle so the opposite sides are congruent to each other.
Long Side:
6x + 6 = 42
subtract 6 from both sides:
6x = 36
divide both sides by 6:
x = 6
Short Side:
5y + 5 = 30
subtract 5 from both sides:
5y = 25
divide both sides by 5:
y = 5
The Equation:
2x + 3y
substitute in the values:
2(6) + 3(5)
do the multiplication:
12 + 15
add the values together:
27
