Answer is C. a^2 ÷ 2 Because diagonals of a square are equal. And area of rhombus formula can be used here because both have all sides equal. Area of rhombus= 1/2(diagonal 1 × diagonal 2) Because diagonals are equal, we write it as : a × a÷ 2 =a^2 ÷2

Answer is C as the question says 3098+1427<5420+2018 and we have to find how much less 3098+1427<5420+2018, which is 5420+2018-3098+1427 and to get this we have to follow the BODMAS rule, which is 7438-4525=2913.

Angle BAC = x + 40 - x => 40 As triangle ABC is an isosceles triangle with AB = AC, angle acb = angle abc = x Therefore, as angle abc + angle acb + angle bac = 180 then, x + x + 40 = 180 =>2x = 180 - 40 =>2x = 140 =>x = 70

Since triangle ABD is congruent to triangle ACD by SSS rule, so the altitude will also be the same. Which means BE=EC, as these are the altitudes of the triangles.
