Question

Sovle The following​

Answer 1

Step-by-step explanation:

the perimeter =2(l+b)

2(385m+215m)

2×600

1200m

1200×15

18000 rs

area of floor =l×b

6m×4m=24m²

square carpet area =s²

4m×4m=16m²

24m²-16m²

tge carpet left is =8m²

Answer 2

Step-by-step explanation:

1. ans

length of rectangular park = 385 m

breadth of rectangular park = 215 m

perimeter of park = 2×(l+b)

= 2×( 385+ 215)

= 2× 600

= 1200

since, cost of fencing park per meter = Rs. 15

therefore, cost of fencing park of 1200 m = 15× 1200= 18,000

2.ans

length of floor = 6 m

breadth of floor = 4 m

area of floor = length × breadth

= 6× 4 = 24 sq m

now, side of square carpet = 4 m

area of square carpet = side × side

= 4×4 = 16 sq m

area of floor that is not carpeted = 24 sq m - 16 sq m = 8 sq m
