Question

the length and breadth of a rectangular field are 100 m and 8 m respectively. find the cost of ploughing and laying seeds in this field at the rate of Rs 1.50 per sq m.

Answer 1

Area of rectangle = length x breadth
Area = 100x8=800sq m
Cost of one sq m =1.50
800 cost = 800x1. 50=


= 3200 answer

Answer 2

Area of rectangle is length X breadth
length = 100 m
breadth= 8m
area is=
$100 \times 8 \\ = 800 \: {m}^{2}$
cost of ploughing and laying seeds per square meter 1.50 Rs
Total cost for the field
$= 800 \times 1.50 \\ = 1200$
Total cost is 1200 Rs
