Question

The ratio of the side lengths of a quadrilateral is 3:3:5:8

, and the perimeter is 380
cm
. What is the measure of the longest side?

20 cm
100 cm
60 cm
160 cm

Answer 1

Answer: D: 160

Explanation:

So if the perimeter is 380, the scale factor is 380/(3+3+5+8)=380/19=20. The longest side is 8, so 8*20= D: 160
