Answer:
204 units²
Step-by-step explanation:
It's a rectangle. Therefore the opposite sides are congruent.
We have the equation:
2x + 4 = 12 subtract 4 from both sides
2x = 8 divide both sides by 2
x = 4
Put the value of x to the expression 4x + 1:
4(4) + 1 = 16 + 1 = 17
Therefore we have the rectangle with dimesions 17 × 12.
The area of the rectangle:
A = (17)(12) = 204
