I know that is q I proved it am sourious
Area of triangle = 1/2(4)(4) = 16/2 = 8
if Area of square then A = 4 x 4 = 16
so answer
B. it's one half the area of square of side length 4 units

Sorry I don’t know any explanation of this
Answer: 60
Step-by-step explanation:
This is done by multiplying length x width x height (6x2x5)
Step-by-step explanation:
such a rectangular prism is in that sense like a cube (or die) : it has 6 sides or surface areas. top, down, front, back, left, right.
to get the total surface area we need to calculate each individual side area and sum all 6 of them up.
since it is a rectangular shape, there are 3 pairs of equal side areas, so, we really need to calculate only 3 different ones :
front and back : each is
10×9 = 90 in², both together are 180 in²
left and right : each is
8×9 = 72 in², both together are 144 in²
top and bottom : each is
10×8 = 80 in², both together are 160 in²
the total surface area of the prism is
180 + 144 + 160 = 484 in²
