Answer 2

Answer:

72.82 cm²

Step-by-step explanation:

Area of triangle = √s(s - a)(s - b)(s - c)

For triangle ABC:

s = (20 + 20 + 10) ÷ 2 = 25

Area = √25(25 - 20)(25 - 20)(25 - 10)

Area = √25(5)(5)(15)

Area = 25√15 cm²

For triangle BCD:

s = (10 + 6 + 8) ÷ 2 = 12

Area = √12(12 - 10)(12 - 6)(12 - 8)

Area = √12(2)(6)(4)

Area = 24 cm²

Find the shaded region:

Shaded region = 25√15 - 24 = 72.82 cm²
