What I want to know-

Is there a Special condition?

Type here each banner is 4 by Type here how much it will cos Type here- $2 per ft

6 ft and its $2 per ft

for two

The ribbon will cost $ _40_

Math is

AWESOME!

$40 will be the total cost of the ribbon.

Step-by-step explanation:

To find the cost of ribbon to be put on the edges of rectangular banner, we need to:

1. Find the perimeter of the rectangle.

2. Multiply the perimeter with the per foot cost to find the total cost.

Let us find the perimeter first:

Perimeter of a rectangle is given as:

Here, the dimensions of rectangle are 4ft by 6ft.

So, perimeter =

It is given that per foot cost is $2.

Total cost of the ribbon =

$40 will be the total cost of the ribbon.

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
