Solve for x round to nearest tenth

15.9 units

Step-by-step explanation:

use the pathagorean theorem to find x.

a^2 + b^2 = c^2

6^2 + b^2 = 17^2

36 + b^2 = 289

-36             -36

=

b = 15.90597372

b = 15.9

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
