Question

The permiter of a rectangle is 68 feet. Find the dimensions of the rectangle if the ratio of the length to width is 9 : 8, Which of the following would be the best equation to use to solve the problem?

A. 2x + 2x =68
B. (9+8) = 68x
C. 9x+8x=68
D. 2(9x) + 2(8x) = 68

Answer 1

The formula to finding the perimeter is...

\(\Huge{2l +2w=P}\)

What would be your answer to this question?

Answer 2

2(9) + 2(8) = 68?

Answer 3

Close. Since we only know the ratio to each other we dont really know its actual length and width so instead it would be \(\large{9x}\) and \(\large{8x}\).

So what would be the answer?

Answer 4

9x + 8x = 68?

Answer 5

It would actually be the format you first had put it in.

\(\Huge{2(9x)+2(8x)=68}\)

Answer 6

So our answer would be.....?

Answer 7

so D is the answer?
