Arectangle length was 4 feet longer than triple the length of it width

Length is 48 ft

The perimeter of a rectangle is equal to the sum of all side’s.
2(lengths)+2(widths)= perimeter
Length=3x+4
Now given the perimeter of 140
3(3x+4)+3(x)=140
9x+12+3x=140
12x+12=140
12x=128
X= 10.7
10.7 is the width

Length=3x+4
Length =3(10.6)+4
Length=31.8+4
Length=35.8
Answer = 35.8
This can only be answered if you were given a perimeter.

Step-by-step explanation:

Given

The first statement implies that:

i.e the components of X

Reading further, we have:

---- The mass of X

--- The relationship between

Required

Two equations to represent the scenario

The two equations are:

--- The relationship between

i.e the components of X

Substitute 25 for X in the second equation

So, the equations are:
