The length of a rectangle is equal to triple the width. Which system fold equations can be used to find the dimensions of the rectangle if the perimeter is 86 centimeters?

Respuesta :

Answer:

Length: 3(10.75) = 32.25 cm

Width: 10.75 cm

Step-by-step explanation:

Length: 3x

Width: x

2(3x)+2x=86cm

6x+2x=86cm

8x = 86cm

x = 86/8

x = 10.75
