Tick the correct answer and justify: ABC and BDE are two equilateral triangles such that D is the mid-point of BC. Ratio of the areas of triangles ABC and BDE is (A) 2:1 (B) 1:2 (C) 4:1 (D) 1:4

DeltaABCandDeltaCDE are two equilateral triangles such that D is the mid -point of BC . The ratio of the areas of DeltaCDEandDeltaABC is 1 : k then k =

Delta POR and Delta QST are two equilateral triangles such that T is the mid-point of QR. Find the ratio of areas of Delta POR and Delta QST .

ABC and BDE are two equilateral triangles such that D is the mid-point of BC. If the area of triangle ABC is 136 cm^2 , then the area of triangle BDE is equal to: ABC और BDE दो समबाहु त्रिभुज हैं जेसे D, BC का मध्य-बिंदु है। यदि त्रिभुज ABC का क्षेत्रफल 136 cm^2 , है, तो त्रिभुज BDE का क्षेत्रफल ज्ञात करे

ABC and BDE are two equilateral triangles such that D is the mid-point of BC. Then, ar (DeltaBDE) = (1)/(2) ar (DeltaABC) .

In figure, ABC and BDE are two equilateral triangles such that D is the mid-point of BC. If AE intersects BC at F, show that ar( Delta ABC) = 2 ar( Delta BEC)
