9. A rectangular garden is 50 m long and 35 m
wide. It has a square rose garden of side 4 m.
It has some play area for children which is
16 m long and 10 m wide. In the remaining
area lawn is grown. Calculate (a) the play area
(b) the area covered by lawn (c) cost of putting
a fence around the garden at 12 per m.​

Answer 1

Answer:

2232m

Step-by-step explanation:

A rectangular garden= 50m + 35m = 85m Formula= 2×( length + breadth)

= 2× ( 50 +35) m

= 2× 85m

= 170m

Perimeter of a square rose garden = 4× sides

= 4× 4m= 16m

Playing area of children= 16m + 10m =26m

But, all the sides aren't equal so, 2×( l+b)= 2×(16+10)m=2× 26m = 52m

Therefore, 170m + 16m = 186m × 12m

= 2232m

Answer 2

Answer:

a

rectangular garden = l x b

=50 x 35

=1750m²

b

area of lawn = L x b

=16 x10

= 160m²

area covered by lawn is 160 m²

c

per m²=12

so, 1750m²=12 x 1750

= 21000
