Step-by-step explanation:
4 x 6 = 24 (side1)
8 x 4 = 32 (side2)
6 × 8 = 24 (side3)
6 x 8 = 24 (side4)
![{6}^{2} + {8}^{2} = 100](https://tex.z-dn.net/?f=%20%7B6%7D%5E%7B2%7D%20%20%2B%20%20%7B8%7D%5E%7B2%7D%20%20%3D%20100)
![\sqrt{100} = 10](https://tex.z-dn.net/?f=%20%5Csqrt%7B100%7D%20%20%3D%2010)
4 x 10 = 40 (side5)
surface area = 24 + 32 + 24 + 24 + 40 = 144ft squared
In a 45 45 90 triangle, the length of each leg = hypotenuse / sq root (2)
each leg = (24 / 1.4142)
each leg = 16.971
Area of a triangle = (base * altitude) / 2
Area of a triangle = (16.971 * 16.971) / 2
Area = 144.007
That dot means multiplication
