Answer:

x= $\sqrt{338}$

Step-by-step explanation:

$a^2+b^2=c^2$

$x^2+x^2=$ $26^2$

$2x^2=26^2$

$2x^2=676$

/2 /2

$x^2=338$

$\sqrt{x^2} =\sqrt{338}$

x= $\sqrt{338}$

Anettt [7]

Answer: 36 cm^2

Step-by-step explanation:

Hello!

We can start by finding the cube root of 216, which is 6. This is the length of each side of the cube.

Now, the area of the base of the cube is equal to 6^2=36 cm^2.

Find the area of this shape. Correct answer will Brainliest

Iteru [2.4K]

Answer:

As shown in picture, this is a trapezoid.

The area of a trapezoid is calculated by:

A = (base1 + base2) x height x (1/2)

To work out A, we need to find out base1, base2, and height.

base1 = YZ = $\sqrt{(Zx - Yx)^{2} + (Zy - Yy)^{2} } = \sqrt{(5 - 2)^{2} + (5 - 5)^{2} } = 3$

base2 = XW = $\sqrt{(Wx - Xx)^{2} + (Wy - Xy)^{2} } = \sqrt{(8 - 1)^{2} + (1 - 1)^{2} } = 7$

Otherwise, the height (distance between base1 and base2) is 4 as shown in picture.

=> A = (3 + 7) x 4 x (1/2) = 20

Hope this helps!
