Answer 1

The length of the rectangular painting will be 25 inches.

Explanation:

Given:

Length of the rope used for rectangular painting = 80 inches

Width of the rectangular painting = 15 inches

To Find :

The length of the rectangular painting = ?

Solution:

Using the rope for decoration Nora can cover the rectangle painting border. That is the perimeter of the rectangle

2(Length x width ) = 80

Her Nora wants the width to be 15 inches , then

2( Length x 15) = 80

2 x length + (2 x 15) = 80

2 x length + 30 = 80

2 x length = 80-30

2 x length = 50

length =
`(50)/(2)`

length =25
