The perimeter of a rectangle is 24ft. The length is 4ft longer than the width. Find the dimensions. write a system linear equation. x is the length and y is the width. Help

Question

hartnn · Answer

since x is 4 feet longer than width,u can write x-y=4
perimeter=2(x+y)=24
to give x+y=12
can u find x and y from these 2 equations?

anonymous · Answer

x - y = 4
x = 4 + y
So you get x in terms of y now.
Plug in this value of x in x + y = 12 and get the answer.
