Question

a rectangular field is 55m long and its breadth is 15m less than its length.find the cost of levelling it at Rs.10.50 per sq.m.

Answer 1

length=55 m
breadth=55-15=40m
area
$55 \times 15 = 825$
cost per sq.m=10.50
cost of 825 sq.m =10.50×825=8662.5

Answer 2

Length=55m
Breadth 15 m less than length
SO, 55-15=40m
Area=l×b=40×55=2200 m square
Cost=2200×10.50=rs 23100
