Question

find area of shaded region​

Answer 1

AREA of Shaded Portion is 244.825 cm²

Step-by-step explanation:

In the figure shown,

Area of ABC = \frac{1}{2}\times Altitude \times base

                      = \frac{1}{2}\times6\times9

                      = 27 cm² '''''''(A)

Area of CBHFED = 26 x 9 - (Area of DEF)

                              = 234 - 27

                              = 207 cm² ""'""(B)

Area of Equilateral FGH = ${\sqrt3}/{4} \times a^{2}$

                                         = ${\sqrt3}/{4} \times 25$

                                         = 10.825 cm² """"(C)

Total Area of Shaded Portion = A + B + C

                                                  = 27 + 207 + 10.825

                                                  = 244.825 cm²

AREA of Shaded Portion is 244.825 cm²
