Find the area of the shaded part​

Answer»

Answer:

28 cm²

Step-by-step explanation:

Radius of semicircle = 7 cm

AREA of semicircle = ½πr² = ½×22/7×7² = 77 cm²

BASE of triangle = 2×7 cm = 14 cm

Height of triangle = 7 cm

Area of triangle = ½×Base×Height = ½×14×7 = 49 cm²

Hence, area of shaded region = (77-49) cm² = 28 cm²
