Step-by-step explanation:

Given:

  • x = 70
  • y = 106

Find: Z to two decimal places

{a}^{2}  +  {b}^{2}  = {c}^{2} \\  {x}^{2}  +  {z}^{2}  =  {y}^{2}  \\  {70}^{2}  +  {z}^{2}  =  {106}^{2}  \\ 4900  +  {z}^{2}  = 11236 \\  {z}^{2}  = 11236 - 4900 = 6336 \\  z = \sqrt{6336}  = 79.60

There are 2 faces 7 x 5

2*(5*7)=2*35=70ft^2

There 2 faces 5 x 5

2*(5*5)=2*25=50ft^2

there are 3 faces 5 x 12

4*(5*12)=4*60=240ft^2

There are 2 faces 7 x 7

2*(7*7)=2*49=98ft^2

Now only we have to sum all of them together

98+240+50+70=458ft^2
