Question

2 metres broad pathway is to be constructed around a rectangular plot on the inside. The area of the plots is 96 sq.m. The rate of construction is Rs. 50 per square metre. Find the total cost of the construction?

A) 20 B) 30 C) 40 D) data is inadequate

Answer 1

Step-by-step explanation:

Total area = (x + 4) (y + 4) = xy + 4(x + y) + 16

= 96 + 4(x + y) + 16

New Area = 112 + 4 (x + y)

∴ We should have either x or y to complete the question

D)data is inadequate
