Second one
1/16
3/8 divided by 1/6=1/16
Half of perimeter (or length+ width) is:
222 mm /2= 111 mm.
111 mm- 60 mm= 51 mm
The width of the rectangle is 51 mm~
It is C I believe have a great day
A) 288 m2
Explanation:
Ok so surface area is just adding up all the area of each faces. Just look at what I do below:
Area of the rectangular base:
10 • 6= 60
Area of the front triangle facing us:
1/2 • 12 • 10= 60
Multiply 60 by 2 cause there is still another similar triangle at the back- 60 • 2= 120
Area of the triangle facing right:
1/2 • 8 • 6= 24
Multiply 25 by 2 case there is still another similar triangle facing on other side(left)
24 • 2= 48
Add them all up together
60 + 120 + 48= 228
MARK ME BRAINLIEST TYSM
have a nice day/night! :DD
