Question

the perimeter of the rectangle is 18a-6b+4c and one of its sides is -3a-4b+2c. Find the other side

Answer 1

The perimeter of the rectangle is 18a-6b+4c and one of its sides is -3a-4b+2c. Find the other side.

Good question,

Here is your perfect answer!

Since Perimeter = 2(l+x)

=) 18a - 6b + 4c = 2(-3a-4b+2c +x)

=) (18a-6b+4c)/2 = (-3a-4b+2c +x)

=) 9a - 3b + 2c = - 3a - 4b + 2c + x

=) 9a+3a - 3b+4b +2c-2c = x

=) 12a + b = x.

Answer 2

Answer:

12a+b

Step-by-step explanation:

As we know that

Perimeter of Rectangle = 2(l+b)

⇒2(-3a-4b+2c + l) = 18a-6b+4c             ... dividing by 2 on both sides we get

-3a-4b+2c + l = 9a-3b+2c

∴ l = 12a+b
