Question

if sinQ+sin²Q=1 then prove that cos²Q+cos²Q=1​

Answer 1

Answer:

Answer-

Side of square = 18cm

Area of square path = 18cm×18cm = 324cm²

Side of tile = 3cm

Area of one tile = 3cm × 3cm = 9cm²

number of tiles can be laid =

= \frac{area \: of \: path}{area \: of \: tile}=

areaoftile

areaofpath

= 324 cm / 9cm

= 36

36 tiles can be laid
