Area of room = length × breadth
Area of room = 13×9 = 117 m²
Let Length of required carpet be x m
Area of carpet = x × .75= .75x m²
Area of carpet = area of room
.75x = 117
x = 117 /.75 = 11700/75= 156
Length of carpet = 156 m
Cost of carpeting 1 m = ₹ 65
Cost of carpeting 156 m = 156 × 65 = ₹ 10140
Hence, the cost of carpeting = ₹10140
Area of room = 13×9 = 117 m²
Let Length of required carpet be x m
Area of carpet = x × .75= .75x m²
Area of carpet = area of room
.75x = 117
x = 117 /.75 = 11700/75= 156
Length of carpet = 156 m
Cost of carpeting 1 m = ₹ 65
Cost of carpeting 156 m = 156 × 65 = ₹ 10140
Hence, the cost of carpeting = ₹10140
