<u>ANSWER: </u>
The length and breadth of the rectangle are 18 m and 12 m.
<u>SOLUTION:
</u>
Let the length and breadth of a rectangle be "l" and "b"
Given,length and breadth of the rectangle are in ratio 3 : 2
Then, length : breadth :: 3 : 2
-- eqn 1
After changing the length and breadth by 1 meter on both sides, length and breadth becomes L+2 and b+2
Now, the ratio of length to breadth is 10 : 7
Length : breadth :: 10 : 7


7l + 14 = 10b + 20
10b – 7l + 20 -14 = 0
10b – 7l + 6 =0 -- eqn (2)
Now, substitute “l” value in (2)


20b – 21b + 12 = 0
-b + 12 = 0
b = 12.
Substitute b value in (2)
10(12) – 7l + 6 = 0
120 + 6 = 7l
7l = 126
l = 18
hence, the length and breadth of the rectangle are 18 m and 12 m.
Answer:
13
Step-by-step explanation:
a pair=2
so 25/each pair of towns
25/2=12+1=13
17 times 0.67 equals 11.39

Answer:
−5+11i
Step-by-step explanation:
(3+6i)−(8−5i)
Subtract 8−5i from 3+6i by subtracting the corresponding real and imaginary parts.
3−8+(6−(−5))i
Subtract 8 from 3. Subtract −5 from 6.
−5+11i
