rectangle given below if its perimeter is 72 cm​

Answer 1

Answer:

perimeter =72=2(l+b)

72=2(5x+4+x−4)

36=6x

x=6 units

Hope it helps you

have a great day ahead

Answer 2

Answer:

perimeter of the rectangle = 2(length + breadth)

Let the length of the rectangle be 'X'

and let the breadth of the rectangle be 'Y

Therefore,

72= 2(X+Y)

36= X+Y

length will be in terms of Y and breadth will be in terms of X

length = 36-Y

breadth = 36-X
