A rectangular field is 3.2 yards long. A fence marking the boundary is 11.2 yards in length. What is the area of the fields in square yard ?
Solution
Correct Answer: Option B
Solution:
দেয়া আছে, আয়তাকার মাঠের length = 3.2 yard এবং পরিসীমা = 11.2 yards
ধরি, আয়তাকার মাঠের Width = x yard
প্রশ্নমতে, 2(x + 3.2) = 11.2
=> 2x + 6.4 = 11.2 x = 2.4
Area of the field = (2.4 \( \times \) 3.2) sq yard
= 7.68 sq yard
