Question

The perimeter of a rectangle is 96 ft. Find the dimensions of the rectangle if the ratio of the length to the width is 7 : 5. Which of the following would be the best equation to use to solve this problem? Please show me how you got the answer too please if possible! Thank you!!
A) 2x + 2x = 96
B) 7x + 5x = 96
C) 2(7x) + 2(5x) = 96
D) 7x/5x = 96

Answer 1

Lets say we have a rectangle. if the ratio is 7:5, we can put the width as 7x, and the length as 5x (or vice versa, it doesn't really matter.) If the perimeter is solved by 2(h+w), we have 2(7x+5x)=96, or 2(7x)+2(5x)=96, which is C

Answer 2

Step-by-step explanation:have a rectangle. if the ratio is 7:5, we can put the width as 7x, and the length as 5x (or vice versa, it doesn't really matter.) If the perimeter is solved by 2(h+w), we have 2(7x+5x)=96, or 2(7x)+2(5x)=96, which is C
