the perimeter of a rectangular painting is 356 centimeters. if the length of the painting is 96 centimeters, what is its width.

sladkih [1.3K]

P = 2(l + w)
p = 356
l = 96

356 = 2(96 + w)
356 = 192 + 2w
356 - 192 = 2w
164 = 2w
164/2 = w
82 = w

check....
p = 2(l + w)
356 = 2(96 + 82)
356 = 2(178)
356 = 356 (correct)

so the width (w) = 82 cm
