Question

plz answer this ques correctly. ​

Answer 1

$\red{solution}$

Given:-

Size of bathroom =10ft. by 8ft

As we know that,

1 ft.=12 inches

Therefore,

Size of the bothroom =(10×12) inch by (8×12) inch= 120 inch by 96 inch

The largest size of tile required =HCF of 120 and 96

By applying Euclid’s division lemma

120=961+24

96=24×4+0

∴HCF=24

∴ Largest size of tile required =24 inches by 24 inches

Now,

No. of tiles required =Area of tileArea of bathroom

∴ No. of tiles required =24×24120×96

No. of tiles required =5×4=20 tiles

Thus the no. of tiles required is 24.

Hence the correct answer is 24 tiles.
