Answer:
D. 420
The area of a triangle is
half of(base× height)
10×16= 160
160÷2=80
That is the surface area of ONE triangle.
multiply 80 by 4 to get 320
then find the surface area of the square by doing length×width to get 100
Finally add them together
320+100=420
The tank of gas will have a density of 35g
Answer:
105 cm squared
First find the area of the rectangle
length x width = area
6 x 15 =90
Now find area of triangle
subtract 11-6 and 15-9 to get the dimensions for the triangle
5 and 6 are the dimensions
Length x height / 2 = area of triangle
5 x 6 = 30
30 / 2 = 15
add the areas together
90 + 15 = 105
105 cm squared
