Mathematics
1 answer:
Stolb23 [73]3 years ago
3 0

Answer:

Step-by-step explanation:

Since we are given the perimeter and the triangle sides we can find the length of the three sides of the square

2(20)+3s=112

3s=72

The total length of the three sides is 72 inches with each side equal to 72/3=24 inches.

The area of the triangles is hb/2 where the base is equal to the side of the square and a height of 16.

The area of the triangle is 24(16)/2=192in^2 and the area of the square is 24(24)=576in^2

And the total area is 192+576=768in^2.

A teacher is making a seating chart in order to group his class of 30 students. He puts 5 students in each group.
Natasha2012 [34]

Answer:

The teacher should divide the amount of students by 5, that way they'll find how many groups they'll have. And the amount of groups they'll have is 6 groups of 5 students, you didn't ask for this part but I decided it'd be best to add it. Hope this helps, have an amazing day you awesome human! ^w^
