The coordinates of rhombus ABCD are A(–4, –2), B(–2, 6), C(6, 8), and D(4, 0). What is the area of the rhombus? Round to the nea

Trava [24]

Answer:

The rhombus ABCD has an area of 22 square units.

Step-by-step explanation:

The coordinates of rhombus ABCD are shown in the image attached below. The area of the rhombus can be found in terms of their diagonals, which are now calculated by Pythagorean Theorem:

$AC = \sqrt{[6-(-4)]^{2}+[8-(-4)]^{2}}$

$AC = 15.620$

$BD = \sqrt{(4-6)^{2}+[0-(-2)]^{2}}$

$BD \approx 2.828$

The area of the rhombus is: ( $AC = 15.620$ and $BD \approx 2.828$ )

$A = \frac{AC\cdot BD}{2}$

$A = \frac{(15.620)\cdot (2.828)}{2}$

$A = 22.087$

The rhombus ABCD has an area of 22 square units.

The precooked weight of a hamburger is 0.25 pounds. Convert this mass to centigrams (cg). (1lb = 16oz, 16oz = 454g)

blsea [12.9K]

.25 lbs= 4oz
4oz = 113.398 g
1g= 100cg

113.398 x 100
= 11339. 8 cg

Hunter-Best [27]

It is the first one, (x,y) to (-x,y) because it is going across the y axis from the positive side, so y stays the same but x becomes negative
