If the sides of a quadrilateral are in the ratio of 3:5:7:9 and the perimeter is 240 inches, find the length of each side

Your equation would be 3x + 5x + 7x + 9x = 240

Combine like terms and that would lead you to 24x = 240

Then divide by 24 on both side leaving you with x = 10

Plug in x and your answer would be 30:50:70:90

Add total units

3+5+7+9=24 uniits

240=24 units

divide both sides by 24

10=1 units

easy

the sides are

30in

50in

70in

90in
