I would like to know if I got this problem correct.
The perimeter of a rectangle is 42ft. the length is 7ft. longer than the width find the dimensions.
Write a system linear equation an solve the resulting system let x be the length and y be the width.
2x+2y=42
y+x=21
y+(y+7)=21
2y=14
y=7
x=y+7=14
What is the length? 7ft.
What is the width? 14ft.
