To solve the problem, we need to suggest two corrective measures eachbow legsround shoulders, which are common postural deformities.
1. Corrective Measures for Bow Legs:
Bow legs (genu varum) is a condition where the legs curve outward at the knees while the feet and ankles stay together.
2. Corrective Measures for Round Shoulders:
Round shoulders is a postural issue where the shoulders slouch forward, often due to weak back muscles and tight chest muscles.
Final Answer:
Two corrective measures for bow legs are: (1) Butterfly Stretch, and (2) Use of orthotics or leg braces.
Two corrective measures for round shoulders are: (1) Wall Angels, and (2) Chest stretching exercises.
A racing track is built around an elliptical ground whose equation is given by \[ 9x^2 + 16y^2 = 144 \] The width of the track is \(3\) m as shown. Based on the given information answer the following: 
(i) Express \(y\) as a function of \(x\) from the given equation of ellipse.
(ii) Integrate the function obtained in (i) with respect to \(x\).
(iii)(a) Find the area of the region enclosed within the elliptical ground excluding the track using integration.
OR
(iii)(b) Write the coordinates of the points \(P\) and \(Q\) where the outer edge of the track cuts \(x\)-axis and \(y\)-axis in first quadrant and find the area of triangle formed by points \(P,O,Q\).
