Question

A rectangular garden is 40 m long and 30 m wide. A two-metre

wide path is to be paved inside the garden along its boundary, using

tiles 25 cm × 20 cm in size. How many such tiles will be required?​

Answer 1

Step-by-step explanation:

REF.Image

Area of path = (40×2)+(30×2)−(2×2)

{−(2×2) for middle area being

counted twice }

=80+60−4=136m

⇒ square files needed = Total area/area of 1 tile

= 136

----------------

25 X 25

----- -----

100 100 = 136 X 16 = 2176

⇒ Total cost = Rs. 21760
