Answer 1

I have answered . See it.
Rest portion of question no 27 is here
27 )Proof :- Since, angles opposite to equal sides of a ∆ are equal .
→ < OAB = < OBA ( since, OA = OB)

→ < OAB =< OBA = x ( say)

By exterior angle property ,
< BOM = 2x
→ < BOM = 2< BAO.....(1)

Similarly,
< COM = 2< CAO......(2)

From (1) and (2), we get
< BOC = 2< BAC.
< BAC = < BOC /2.



Let the length , breadth and height be 4x m, 3x m and 2x m.

According to question, the TSA of the cuboid = 4212 m^2

Since, TSA of a cuboid = 2(lb + bh + lh) sq. units

→ 2(12x^2 + 6x ^2 + 8x ^2) = 4212
→26x ^2 = 2106
→ x^2 =81
→ x = 9.

Hence , length = 4x m =36m

breadth = 3x m= 27x m
height =2x m = 12x m
