Answer:
Area of the shaded region = 51 cm²
Step-by-step explanation:
Area of the smaller pentagon ABKHG = 17 cm²
Since, B is the midpoint of side AC,
Scale factor used to enlarge the sides =
=
= 2
Therefore, area scale factor of both the pentagons = (Dimensional scale factor)²
2² =
4 =
Area of bigger pentagon AFEDC = 4 × 17
= 68 cm²
Area of the shaded region = Area of the bigger pentagon - Area of the smaller pentagon
= 68 - 17
= 51 cm²

First, we need to equalize the denominator. If the denominator multiplies by (x+1), so does the numerator. If the denominator multiplies by (x-1), so does the numerator.
