1. Find<br> the area of each figure to the nearest tenth.
ELEN [110]

Area = 85ft²

To find the area of the given square you can use the following equation

Area = Side^2\\Area = 8^2\\Area = 64

To find the missing side of the given triangle, you will have to use Pythagorean's theorem

Short^2 + Long^2 = Hypotenuse^2\\Short^2 + 8^2 = 10^2\\Short^2 + 64 = 100\\Short^2 = 100 -  64\\Short^2 = 36\\Short= \sqrt{36} \\Short= 6 \\

Now that we know what both sides are we can use the following equation to get the area of the triangle

Area = \frac{Side*Side}{2} \\Area = \frac{6*8}{2} \\Area = \frac{42}{2} \\Area = 21 \\

After that, we can add both areas together and get the following

21+64=85

Use formulas to find the lateral area and surface area of the prism.
TiliK225 [7]

Step-by-step explanation:

Finding surface area

To find the surface area of a prism, use the formula SA=2B+ph, where SA stands for surface area, B stands for area of the base of the prism, p stands for the perimeter of the base, and h stands for the height of the prism. Since this is a triangular prism, substitute the area formula of a triangle for B.
