which can be paved on the floor of a room 2m
50 cm long and 1 m 50 cm broad. Also find the
number of such slabs to pave the floor.
(a) 40, 18 (b) 30, 15
(c) 50, 15 (d) 20, 25

Answer 1

Answer:

(c) 50,15

Step-by-step explanation:

l= 2m 50cm =200+50

= 250cm

b= 1m 50cm =100+50

= 150cm

Let side of the square slabs be s

Area of the floor = lxb

= 250x150

= 37500 cm.sq.

Size of largest square slab = HCF of 250 and 150 = 50cm

Area of one glass slab = 50x50

= 2500 cm.sq.

No. of slabs = 37500/2500

= 15 square slabs

Therefore, the correct option is (c) 50,15
