Answer : W = 14.375 inches
L = 38.125 inches
Step-by-step explanation:
Suppose the length of the rectangle is : L
and Width of the Rectangle is : W
As per the the given question
L = 3W -− 5 ---------- (1) // Length is five less than three times its width
Given Perimeter = 105 inches
2( L + W ) = 105 ---------- (2)
Put the value of L from equation (1) to equation (2)
2( 3W -− 5 + W)= 105
6W -− 10 + 2W = 105
8W -− 10 = 105
8W = 115
W = 14.375
Put the value of W in the equation (1)
L = 3W -− 5
L = 3*∗14.375 -− 5
L = 43.125 -− 5
L = 38.125
Answer : W = 14.375 inches
L = 38.125 inches
