Answer:
88 cm²
Step-by-step explanation:
w = x
l = x + 3
P = 38
We know that
, so we substitute known values:

Therefore, we know that the width (x) is 8 cm and the length (x + 3) is 8 + 3 = 11 cm. To verify, we can check that the perimeter equals 38:
8 + 11 + 8 + 11 = 38. <em>Check.</em>
Thus, the area of the rectangle is:

Therefore, the area is 88 cm².
