Answer:
<em>The width is 4 cm</em>
<em>The length is 12 cm.</em>
Step-by-step explanation:
<u>Area of a rectangle</u>
Given a rectangle of width W and length L, its area is calculated as follows:

The area of the given rectangle is 48 cm^2, and the length is three times the width, thus:
L = 3W
Substituting into the formula of the area:


Simplifying:

Solving:


The width is 4 cm. Find the length:
L=3W=3*4= 12
The length is 12 cm.

Answer:
y=3x+2
Step-by-step explanation:
y=mx +b, m is slop, slop is given and = 3--->
y=3x+b, lets find b
substitute x and y coordinates of given point into y=3x+b---->
2=3 x 0 + b ; solve for b
b=2----->
y= mx+b is y=3x+2
