Solution

The correct option is B
₹. 105

Let n be the number of mats.

Base of mat = 3 cm

Height of mat = 4 cm

Area of one mat = base $\times$ height

Area of hall = Area of mat $\times$ number of mats

$\Rightarrow 180 = 4 \times 3 \times n$

$\Rightarrow n = \frac{180}{12} = 15$

Given that 1 mat costs = ₹. 7

Then 15 mats costs $= 7 \times 15 = ₹ . 105$
