Question

. A verandah is 40 m long and 15 m broad. It is to be paved with stones, each measuring 6 dm by 5 dm. Find the number of stones required.​

Answer 1

Answer:

Hey let's solve this problem

Step-by-step explanation:

Area of Verandah=l×b

Area of Verandah=40×15=600m

2

Area of each stone=6dm×5dm=30dm

2

=30×10

−2

m

Number of stone =

Areaofeachstone

AreaofVerandah

Number of Stones=

30×10

−2

600

Number of stones=2000

Answer 2

Answer:

Here

Given : Measures of Verandah :

Length (L) = 40 M ; Breadth (B) = 15 M

Measures of stone :

Length (l) = 6 dm = 0.6 M ;

Breadth (b) = 5 dm = 0.5 M

Now,

no. of stones to be paved =

Area of Verandah/Area of stone

= L*B / l*b

=40*15 / 0.6*0.5

=600/ 0.30

= 2000

Hence we need 2000 stones for Verandah be paved
