Question
A mat in the shape of a parallelogram has a height of 4 cm and a base of 3 cm. How much would it cost to cover a parallelogram shaped hall with an area of 180 sq. cm with mats, if each mat costs Rs.7?
Answer: Option A
:
A
Let n be thenumber of mats required
base of mat = 3 cm
height of mat = 4 cm
Area of the parallelogram= base ×height
Area of hall = Area of mat × number of mats
⇒ 180 = 4 x 3 x n
⇒n=18012=15
Given that eachmat costs Rs. 7
Then the cost of 15 mats costs = 7 x 15 = Rs.105
