The perimeter of a rectangular is 96 ft. the ratio of the length to the width is 7: 5. what are the dimensions of the rectangle a. 2x + 2x = 96 b. 7x + 5x = 96 c. 7x + 7x + 5x + 5x = 96 d. 7x/5x = 96

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
