the length of a rectangular picture frame is 3 centimeters less than twice the width. the perimeter is 78 centimeters. find the

Natalka [10]

Let the width be x
width = x
length = 2x - 3

Perimeter = x + 2x - 3 + x + 2x - 3 = 6x - 6

6x - 6 = 78
6x = 78 + 6
6x = 84
x = 14 cm

2x - 3 = 2(14) - 3 = 25cm

The width is 14cm and the length is 25cm
