Answer:
Area of two bedrooms= 10 x sq.m Area of kitchen
= 5y sq.m 10x + 5y = 95 2x + y =19
Also, x + 2 + y = 15 x + y = 13 2.
Length of outer boundary = 12 + 15 + 12 + 15 = 54m 3.
On solving two equation part(i) x = 6m and y =7m area of bedroom = 5 x 6 = 30m
area of kitchen = 5 x 7= 35m 4.
Area of living room = (15 x 7) - 30 = 105 - 30 = 75 sq.m 5.
Total cost of laying tiles in the kitchen = Rs 50 x 35 = Rs 1750
