Question

the length of a rectangle is 5A + 5B + 9C and breadth is A -2B - C then find the perimeter of rectangle​

Answer 1

HEY BUDDY....HERE'S YOUR ANSWER.....

Length =5A+5B+9C

Breadth=A-2B-C

Perimeter of the rectangle =2(l+b)

=2[(5A+5B+9C)+(A-2B-C)]

=2[5A+5B+9C+A-2B-C]

=2[6A+3B+8C]

=12A+6B+16C units.

So,the perimeter of the rectangle is

12A+6B+16C units.
