Question

A mat shaped in 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 area 180 sq. cm with mats, if 1 mat costs Rs. 7?

• A. Rs. 105
• B. Rs. 115
• C. Rs. 135
• D. Rs. 95

Answer 1

The correct option is A

Rs. 105

n = number of mats

Area of the parallelogram = b x h

180 = 4 x 3 x n

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

Given that 1 mat costs = Rs. 7

Then, 15 mats costs = 7 x 15 = Rs.105
