Question

The length of s is 2/3 the length of t. If s has an area of 368 cm squared find the perimeter of the figure

Answer 1

the correct answer is 78.2 hope this helped 

Answer 2

`s = (2)/(3)t \\\ (2)/(3)t*t = (2)/(3)t^2 \\\ (2)/(3)t^2 = 368 \\\ t^2 = \frac {3}{2}368 \\\ t^2 = 552 \\\ t \approx 23.5 \\\ s \approx 15.6 \\\ P \approx 78.2`
