Area=legnth times width
192=(9+x)(13+x)
solve
expand
192=117+22x+x^2
minus 192 both sides
0=x^2+22x-75
factor
0=(x-3)(x+25)
set to zero
x-3=0
x=3
x+25=0
x=-25
not possible since that gives negative legnths and widhs
increased by 3
shorter is 9
9+3=12
C is ansre
$942.50.
$14,500 x 0.065 = $942.50
6.5% = 0.065
Answer:
Finding the areas of each of the rectangles and squares of the net of a rectangular prism and adding up those areas gives the surface area or total surface area of the prism. For example, if the length of one side of the cube 4 units then the area of one its face is 4 × 4 = 16 square units.
