B
Step 1: Perimeter of a rectangle = 2(l + w)[Formula for the perimeter.]
Step 2: 2(l + 2) = 18[Substitute the value of width = 2 m.]
Step 3: (l + 2) = 182[Divide each side by 2.]
Step 5: l + 2 = 9[Simplify.]
Step 6: l = 7 m[Subtract 2 from each side and simplify.]
Step 7: Area of a rectangle = l × w
[Formula for the area.]
Step 8: = 7 × 2[Substitute the value of l and w.]
Step 9: = 14 m2[Simplify.]
Step 10: The area of the rectangle is 14 m2.
