The length of a rectangle is 4 centimeters less than three times the width. the perimeter of the rectangle is 88 centimeters. what are the dimensions of the rectangle?

Respuesta :

2 [ (x) + (3x - 4) ] = 88

2 [ x + 3x - 4 ] = 88

2 [ 4x - 4 ] = 88

4x - 4 = 44

4x = 40

x = 10 cm [ width]

3(10) - 4 = 26 cm [length]
