What is the rectangular field?
Answer:(3) 33 m
The breadth of the rectangle = 25 m
Cost of a grass bed on this field = Rs.12375
Cost of per sq. m. = Rs.15
Therefore, the area of the field = 12375/15
= 825 m2
Let be the length is X mitre.
Area of rectangle = Length x breadth
X x 25 = 825
X = 825/25
X = 33 mitres
Hence, the length is 33 mitres of a rectangle field.
