Answer 1

Answer:

1. perimeter of rectangle = length × breadth

28×22

616m

2. length =600cm

breadth= 200cm

length of square tiles = 25cm

no. of tiles= area of kitchen÷area of square tiles

n= 600×200÷25×25

n=120000÷625

n=192

3.length=34m

breadth = 21m

perimeter = l×b

34×21

714m

4. volume= l×b×h

8×6×2

=96cm³

5. volume= a³

10³

1000cm³

6. volume= l×b×h

9×8×4

288cm³
