Question

11and 12question plz solve it

Answer 1

11. Since length of the tangents drawn from a point are equal. AB+ CD= AP+BP+ CR+RD = AS + BQ+ CQ+ DS = (AS+DS) + ( BQ+CQ) = AD+ BC

12. a³= 125cm³
So a = 5cm { a is the side length of cube)

Dimensions of new cuboid formed;
Length= 10cm Breadth= Height= 5cm

Surface area of cuboid= 2(lb+bh+lh)
=2(50+25+50) = 250cm²

Answer 2

AP = AS .....(i)
BP = BQ ii
CR = CQ ...iii
DR = DS ...iv

Tangents from same point to a circle are equal

Now adding all eq.
AP+BP+CR+DR = AS+BQ+CQ+DS
(AP+BP) + (CR+DR) = (AS+DS) + (BQ+CQ)
AB + CD = AD+BC
