Answer:
Perimeter of the rectangle = 14x + 8y - 2 units.
Step-by-step explanation:
Given:
Length of the rectangle = 2x - 3y + 1
Breadth of the rectangle = 5x + 7y - 2
To find:
Perimeter of the rectangle
Solution:
Perimeter of the rectangle = 2(L + B) units
to find (L + B),
= 2x - 3y + 1 + (5x + 7y - 2)
= 2x - 3y + 1 + 5x + 7y - 2
= 7x + 4y - 1
Perimeter of the rectangle = 2(L + B) units
= 2(7x + 4y - 1)
= 14x + 8y - 2 units.
