So if I had this problem I would multiply 21 x 34= 714 then I would divide it by 14 which would get me 51. There would be 51 blocks in each group!
You need to 8 + 4 = 12 and take the half of 12 and start at -4 and count up 6
Answer:
6
Step-by-step explanation:
Typically these kinds of problems are solved using Venn Diagram.
Let’s solve it differently.
Here, we add the individual subject students and subtract the dual subject students and then add the triple subject students that would give us the count of all the students. If that’s more than number of students then there’s something wrong with the given data. If that’s exactly equal to number of students then all the students have taken some course(s) or the other. If that’s less than number of students then subtracting this from number of students would give us the count of students having not taken any course(s).
Thus, the count of students having taken some courses or the other is:
20+18+16–7–7–9+3 = 57–23
= 34
Subtracting it from 40 gives us 6, which is the count of students not taking any course(s).

Answer:
1144cm²
Approx. 1100cm²
Step-by-step explanation:
Area of rectangle=
L×B
34×20 = 680cm²
Area of semi-circle=
πr²
3.14 × (10)² = 314cm²
Area of triangle=
½b×h
b = 49 - 34 = 15
<u>2</u><u>0</u><u> </u><u>×</u><u> </u><u>1</u><u>5</u> = 150cm²
2
Area of shape =
680 + 314 + 150 = 1144cm²
approx. 1100cm²
