Answer:
The length of the rectangular painting will be 25 inches.
Step-by-step 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 = [tex]\frac{50}{2}[/tex]
length =25
