Answer
SELF-PRACTICE — the source book printed no answer.
Nothing is invented here, so this question has no answer on record.
Explanation
I. $l=40$ yards. Perimeter = 140 yards. $$\begin{aligned} 2(l+b)=140 & \Rightarrow l+b=70 \\ & \Rightarrow b=(70-l)=30 \text { yards. } \end{aligned}$$ Area of the field $=(40 \times 30)$ sq. yds $=1200$ sq. yds.
