pls tell me all the questions ..fast

Answer 1

Q4 → s²/S²=4/9
so,
s/S=2/3
8/S=2/3
S=8×3/2
S=12 cm

so, a is correct

-------------------------------

Q5 → let the park and path together be a big square and park be the small square
so,
side of small square = s = 30 m
side of big square = S = 32 m
so,
area of path = area of big square - area of small square = S² - s² = (32)² - (30)² = 1024 - 900 = 124 m²

so, c part is correct
