For question 2, the answer is 120 cm^2
The formula is SA = b + 1/2 ps
p = perimeter
s = slant height
this is a square, so all the sides are equal. So 6 cm x 4 = 24 cm, this is the perimeter of the base.
then multiply this by the slant height, and you get 192.
192 x 1/2 = 96.
96 + 24 (the area of the base) = 120.
120 = 24 + (1/2 x 24 x 8)
Answer : 5x + 32
Step-by-step explanation:
3(x + 4 ) +2 (x + 5)
3x + 12 + 2x + 10
5x + 32
Answer:
Option C
Step-by-step explanation:
See here the net seems like a equilateral triangle
- And another equilateral traingle is inscribed in it
- So 4 equilateral triangles
Hence option C
