Answer:

The correct answer is: a = 10 cm, b = 18 cm and c = 20 cm

Step-by-step explanation:

We will use triple proportion:

a : b : c = 5 : 9 : 10     from which is:

a = 5 k , b = 9 k and c = 10 k  where k is coefficient of proportion.

Formula for perimeter is:

P = a + b + c

When we replace value for a = 5 k , b = 9 k and c = 10 k in the formula for P we get:

5 k + 9 k + 10 k = 48  => 24 k = 48 => k = 48/24 = 2

Finally we get:

a = 5 · 2 = 10 cm

b = 9 · 2 = 18 cm

c = 10 · 2 = 20 cm

There are  156 rows of trees altogether.

<u>Step-by-step explanation:</u>

Given that for every 11 rows of Red delicious , they plant 3 rows of Royal Gala.

Thus for 1 row of Royal Gala there would be 11/3 rows of Red delicious.

Number of rows of Royal Gala=18

corresponding\ number\ of\ Red\ delicious\ = 11/3 \times 18=11\times 6=66

For 11 rows of red delicious,they plant 7 rows of yellow delicious.

Thus for 1 row of Red delicious,there would be 7/11 rows of yellow delicious.

For 66 rows of red delicious there would be

7/11\times66=7\times 6=42 rows\ of\ yellow\ delicious

For 11 rows of red delicious,they plant 5 rows of Braeburn

for 1 row of red delicious,they would plant 5/11 rows of Braeburn.

For 11 rows of red delicious,they would plant

5/11\times 66=5\times 6=30\ rows\ of\ braeburn

Total rows of trees=66+42+30+18=156
