Question

B. Find the perimeter of a rectangle whose length and breadth are (2x-3y) units and (9x-4y)
units respectively.​

Answer 1

22x-14y

Step-by-step explanation:

length=2x-3y, Breath=9x-4y

so perimeter=2(l+b)

=2(2x-3y+9x-4y)

=2(11x-7y)

=2×11x-2×7y

=22x-14y

Answer 2

●Length =2x-3y

●breath= 9x-4y

》so, perimeter of a rectangle = 2(l+b)

》2(2x-3y+9x-4y)

》2(11x-7y)

》2×11x-2×7y

》22x-14y
