A) A rectangle is 8.7 cm long and 5.4 broad.
Mama L [17]

Step-by-step explanation:

a)i) perimeter= side+side+side+side

perimeter=8.7+8.7+5.4+5.4=28.2cm

ii) area=h×b

area=8.7×5.4=46.98cm²

b)i) perimeter=20.35+20.35+17.84+17.84

perimeter=76.38cm

ii)area=20.35×17.84

area=363.044cm²

c) area of rectangular field=937.125m²

Length=36.75m

i)Breadth=937.125÷36.75=25.5m

ii)perimeter=36.75+36.75+25.5+25.5

perimeter=124.5m

Stella [2.4K]

Answer:

8 different combinations are possible.

Here, we have 2 different combinations for each time.

And the player comes out to bat 3 times.

So, total number of combinations are:

2^{3} i.e. a total of 8 number of times.

Let a hit is termed as 'H' and an out is termed as 'O'.

Total combinations are:

{HHH, HHO, HOH, HOO, OHH, OHO, OOH, OOO}

Kindly have a look at the tree diagram attached in the answer area.

In starting, there are 2 combinations possible, i.e. 'O' and 'H'.

After 'O' , 2 possible i.e. 'O' and 'H'.

After 'H' , 2 possible i.e. 'O' and 'H'.

and so on....
