Question

perimeter (length of a boundary) of a rectangle is​

Answer 1

Answer:

Solution: Given length l is 120 inches; breadth b is 85 inches We know that the perimeter of a rectangle is equal to twice the sum of its length and breadth. Hence Perimeter of a rectangle = 2(l+b).

Answer 2

2(l+b)

Step-by-step explanation:

The perimeter of a rectangle is twice the sum of its lenght and breath. Perimeter=2(lenght+breath) units. Perimeter is the sum of the lenghts of the boundaries of the rectangle.Hence the perimeter of a rectangle has the same units as the lenght of the rectangle.
