What is the area of the base?

MAXImum [283]

Answer:

24 in²

Step-by-step explanation:

Hello there!

the figure shown is a triangular prism

The base is the triangle

So we need to find the area of the triangle using this formula

$A=\frac{bh}{2}$

where b = base and h = height

The base (triangle) has a base length of 8 inches and a height of 6 inches

Having found the information we needed, we plug it into the formula

$A=\frac{6*8}{2} \\6*8=48\\\frac{48}{2} =24\\A=24in^2$

So the area of the base is 24 in²

The lengths of the sides of a right triangle are a and b, and the hypotenuse is

mamaluj [8]

A^2+b^2=c^2
(2sqrt3)^2+b^2=16
12+b^2=16
solve for b
b=2
Now triangle area is A=1/2 bh
so
A=(1/2)(2)(2sqrt3)
A=2sqrt3

$z^{2} + 8z + 6$

Simplifying:

z + (z + 6)z + z + 6=

$z + z^{2} + 6z + z + 6$ =
