Answer 2

Answer:  24

Step-by-step explanation:

Given : The height of first storey of a building  = 3.25 m

Since 1 m = 100 cm

Then, 3.25 m = 325 cm

Also, the height of riser = 13 cm

Then, the number of riser can be made = $\dfrac{325}{13}=25$

Now, the number of treads can be made = 25-1=24

Hence, the number of treads required is 24.
