Hello!
You can make 2 equations based on what you know
2l + 2w = 190
w = 0.25l
Put w into the first equation
2l + 2(0.25l) = 190
Distribute the 2
2l + 0.5l = 190
Combine like terms
2.5l = 190
Divide both sides by 2.5
l = 76
Put l into the second equation
w = 0.25(76)
Multiply
w = 19
The length is 76 and the width is 19
The answer is
2l + 2w =190
w = 0.25l
Hope this helps!
