Step-by-step explanation:
<u>For old circular garden:</u>
take the radius as r.
then use the formula to find area of circle: πr² ......this is old garden area.
<u>For new enlarged garden:</u>
the radius is twice the old radius so, radius = 2 * r = 2r ......enlarged radius
now find area for this new garden: π(2r)² → 4πr²
In common fractions: (old garden)/(new garden)
: ( πr² ) / ( 4πr² )
: 1/4

We'll work in pounds.
Income on the 80%:
75 * 0.80 * 0.80 = 48 pounds
Income on the 20%:
75 * 0.20 * (2/3) = 10 pounds
Profit = 48 + 10 - 35 = 23 pounds
Margin is profit over sales; percentage profit is profit over cost
PP = 23 / 35 = 65.7%
