Composite figure is made up of 4 triangles and a square.
Area of Square = Length x Length
Area of Square = 12 x 12
Area of Square= 144 cm²
Area of triangle = 1/2 x base x height
Area of triangle = 1/2 x 12 x 8
Area of triangle = 48 cm²
Area of 4 Triangles = 48 x 4
Area of 4 Triangles = 192 cm²
Total Area = 144 + 192 = 336 cm²

Answer:
84 students
Step-by-step explanation:
We know that the ratio of boys to girls is 4 : 3, and we know that the actual number of boys is 48, so let's set up a proportion:
, where x is the number of girls in the club
Cross-multiply:
4x = 48 * 3 = 144
x = 144/4 = 36
Thus, there are 36 girls in the club.
Don't forget to check back with the question! It's asking for the total number of students, so we need to add 36 to 48:
36 + 48 = 84
Therefore, our answer is 84 students.

Answer:
4
Step-by-step explanation:
Simply, replace the values we are given for x=4 and y=(-2) into the expression.
5(x + y) – 3(x – y)
5*(4 - 2) - 3*(4 -2)
20 - 10 - 12 + 6 = 4
