The square shown has sides of length 7z^5 decimeters. Find its area

VikaD [51]

For this case we have that by definition, the area of a square is given by:

$A = l ^ 2$

Where:

l: It's the side of the square

We have, according to the statement data, that:

$l = 7z ^ 5 \ dm$

Then, the area is given by:

$A = (7z ^ 5 \ dm) ^ 2$

By definition of power properties we have to:

$(a ^ n) ^ m = a ^ {n * m}$

So:

$A = (7z ^ 5 \ dm) ^ 2 = 49z^{5 * 2} \ dm ^ 2 = 49z^{10} \ dm ^ 2$

Answer:

The area of the square is: $49z^{10} \ dm ^ 2$

zhuklara [117]

Answer:

$275

Step-by-step explanation:

This is what I got:

You first convert 2.75% into 0.0275

You then multiply 500 x 0.0275 = 13.75

Finally you multiply 13.75 x 20 = 275

so the answer should be 275

Find the area of a quadrilateral ABCD in which AB = 3 cm, BC = 4 cm, CD = 4 cm, DA = 5 cm and AC = 5 cm.

melamori03 [73]

Answer:

$6+2\sqrt{21}\:\mathrm{cm^2}\approx 15.17\:\mathrm{cm^2}$

Step-by-step explanation:

The quadrilateral ABCD consists of two triangles. By adding the area of the two triangles, we get the area of the entire quadrilateral.

Vertices A, B, and C form a right triangle with legs $AB=3$ , $BC=4$ , and $AC=5$ . The two legs, 3 and 4, represent the triangle's height and base, respectively.

The area of a triangle with base $b$ and height $h$ is given by $A=\frac{1}{2}bh$ . Therefore, the area of this right triangle is:

$A=\frac{1}{2}\cdot 3\cdot 4=\frac{1}{2}\cdot 12=6\:\mathrm{cm^2}$

The other triangle is a bit trickier. Triangle $\triangle ADC$ is an isosceles triangles with sides 5, 5, and 4. To find its area, we can use Heron's Formula, given by:
