Question

plz answer in given fig ab=1/2bc where bc =14cm find
(1)area of quad aefd
(2)area of trianhle ABC
(3)area of semicircle​

Answer 1

Answer:

Step-by-step explanation:

BC = 14 cm

AB = BC/2 = 14/2 = 7 cm

BC = Diameter = 14 cm

BE = Radius = 7 cm

AE = AB + BE = 7 + 7 = 14 cm

AD = EF = BC = 14 cm

Area of Square AEFD = 14 * 14 = 196 cm²

Area of Δ ABC = (1/2) * 14 * 7  = 49 cm²

Area of Semi Circle = (1/2)π R²

= (1/2) (22/7) * 7²

= 77 cm²

Area of Shaded region = 196 - 49 - 77

= 70 cm²
