Answer:
Each student can have 1 pencil each
Step-by-step explanation:
Since there are 4 packs of pencils with 12 pencils in each pack, you want to multiply 12 by 4 which equals 48 pencils in total. Because there are 25 students, each student can have 1 pencil. They can't have 2 pencils each though since 25 times 2 is 50 and 48 is less than 50.

Answer:
1. A = 40 units²
2. A = 72 units²
3. B) 45
Step-by-step explanation:
1. This shape comprises 4 congruent triangles with base of 5 units and height of 5 units.
Area of a triangle = 1/2 x base x height
Therefore, area of polygon = 4(1/2 x 5 x 4)
= 40 units²
2. This shape comprises two pairs of congruent triangles.
Area of a triangle = 1/2 x base x height
Therefore, area of polygon = 2(1/2 x 2 x 6) + 2(1/2 x 10 x 6)
= 72 units²
3. Count the number of shaded squares:
9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 45 units²
