A worker at store is making a rectangular frame. The perimeter of the frame is 240 inch the length of frame is 75 inches Determine what the width of the frame needs to be

width = 45 inches

Step-by-step explanation:

Perimeter = 2l + 2w

240 = 2*75 + 2w

240 - 150 = 2w

90 = 2w

w = 90/2 = 45

answer:

what is your question that you ask

step-by-step explanation:

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.
