Area of triangle = 1/2 × base × height
so,
24=1/2*base*4
base=12m
The algebraic expression that will represent the perimeter in centimeters of the given rectangle is: 
<em><u>Recall:</u></em>
Perimeter of a rectangle = 2(L + W)
<em>Given the following dimension of a </em><em>rectangle</em><em>:</em>
- width (W) = (8.4x + 2.2) cm
- length (L) = (4.5x + 3.4) cm
To find the expression that represents the perimeter, plug in the given values into the formula for perimeter.
Perimeter = 
Perimeter = 
Perimeter = 
Perimeter = 
Therefore, the algebraic expression that will represent the perimeter in centimeters of the given rectangle is:

Answer:
D=3x+5, I=4x+8, -1x-3
Step-by-step explanation:
You don't know how many chocolates are in the boxes, so that's x. Always look at "and" and think + something. You know how many extra chocolates there are so you don't need to put the x. Remember, and=plus. Remember the equation is Mx+b.
The two expressions together is 3x+5=4x+8. Move the 4x to the other side with 3x+5 and make it negative. Same for eight. Hopefully that helps.
