Option C 20
GOOD LUCK FOR THE FUTURE! :)
In a parallelogram, opposite angles are congruent and consecutive angles are supplementary.
3x - 15 = 2x + 24
3x - 2x = 24 + 15
x = 39 <===
the area is 180 cm. to find the perimeter you would do 15+15+14+14 to get 54 cm. So for area you do (l×w) which is 15×14=180.
