Question

Find the cost of turfing a lawn, 25 m by 20m at Rs 15 per sq m.
A tailor makes 9 frocks out of 12m of cloth. For 75 frocks how much cloth should he buy?​

Answer 1

Step-by-step explanation:

1. perimeter of lawn=2(l+b)

=2(25+20)

=90

cost per sp m.= 15

cost of lawn= 90×90=8100×15

=1,21,500

2. cloth needed for 1 frock = 12divided by 9= 1.3

cloth for 75 frocks= 75×1.3=97.5
