Problema Solution
The perimeter of a rectangle is 26ft. The length is 9 ft. longer than the width. Find the dimensions. Write a system of linear equations and solve the resulting system. Let x be the length and y be the width.
Write the first equation
2x + 2y = 26
Write the second equation
x = y + 9
what is the length? __ft.
what is the width? __ft.
Answer provided by our tutors
2x+2y=26
x=y+9
substituting second equation in the first gives us
2y+18+2y=26 => 4y = 8 => y = 2
=> x = 2+9 = 11
what is the length? 11__ft.
what is the width? _2_ft.
