Answer:
3 with a few left over so 4
Step-by-step explanation:
Area of the triangle = (1/2)*base* height = (1/2)*3*6 = 9 sm²
We have 4 triangles like this one ,
so area of 4 triangles = 9*4 = 36 cm².
Area of the square = 3*3 = 9 cm²
Surface area here means area all triangles + area of the square =36 +9 =
= 45 cm ²
Answer is 45 cm².
800+16x=720+21x
80+16x=21x
80=5x
X=16
So 16 hours :)
Pretty sure it’s bottom left.
