Hey there!!
Total length of the fabric bought = 3 1/4 yards
First, let's convert this mixed fraction to improper fraction
3 1/4 = 13/4
The total cost for 13/4 yards = $13
Find cost per yard
Let's take the cost per yard as ' x '
Then, 13/4 yards = 13x / 4
Let's get this into an equation -
13x/4 = 13
Multiply by 4 on both sides
13x = 52
Divide by 13 on both sides
x = 52 / 13
x = 4
The cost per yard = $4
Hope my answer helps!
Assuming a rectangular monitor
the area of a rectangle is
A=B*H
B-base
H- Height
multiply 14.86 by 11.15
sorry, then make a unit conversion into m^2
The surface area is all the areas of all the exterior faces in a 3D shape.
Doing all the possibilities, 4 * 5 * 2 , 5 * 7 * 2, 4 * 7 * 2 = total surface area
40 + 70 + 56 = 166 m^2
The answer is 2. 166 m^2
