Answer:
16 degrees
Step-by-step explanation:
180 degrees = 164 degrees + x,
x = (180 - 164) degrees,
x = 16 degrees
Ok so we are gonna find the area or the rectangles on the object
Area of rectangle 1 = length x width
= 6 x 20
= 120 m square
Multiply the area of rectangle 1 by 2 because there are two same shaped rectangle.
120 x 2
=240 m square
Area of rectangle 2 = 30 x 6
= 180 m square
Multiply the area of rectangle 2 by 2 because there are two same shaped rectangle.
180 x 2
=360 m square
Area of rectangle 3 = 30 x 20
= 600 m square
Multiply the area of rectangle 3 by 2 because there are two same shaped rectangle.
600 x 2
=1200 m square
Then add all the area of the rectangles.
240 + 360 + 1200
= 1800 m square
Therefore the surface area is 1800 m square
We will see that 20 children can get a serving.

How to divide fractions?</h3>
To see how many children can get a serving we need to take the quotient between the total amount of grapes and the amount of grapes needed for each serving.
We know that there are 5 bunches of grapes, and each serving needs 1/4 bunches, then we need to solve:

Notice that we can write 5 as a fraction:
5 = 5/1
then:

Now, the two numbers in the middle (both ones) remain on the denominator, while the other 2 conform the numerator, then we have:

So 20 children can get a serving.
