9. A rectangle has an area of 45m²

love history [14]

Answer:

$Lenght=3\,m$

Product of length and width= $45$

Step-by-step explanation:

The product of the length and width of the rectangle is called the area of the rectangle.

Area of the rectangle= $45\,m^2$

$Width=15\,m$

Area of the rectangle= $Length\times Width$

$45=Length\times 15\\\\Length=\dfrac{45}{15}\\\\ Length=3\,m$

The product of the Length and Width of the rectangle is :

$=3\times15\\\\=45 m^2$ i.e area of the rectangle.

Find the distance and midpoint for (2, 0, -2) and (5, -4, 6)

sweet-ann [11.9K]

Hi, It is well simples:

The distance between two points is :

d( A, B) = √[ (xb - xa)^2+(yb - ya)^2+(zb - za)^2]

Then,

A = (xa, ya, za )

B = (xb , yb , zb)

We know:

A = ( 2 ,0 ,-2)

And,

B = (5 , -4 , 6)
___________

xb - xa = 5-2 <=> 3

yb - ya = -4 - 0 <=> -4

zb - za = 6 - (-2) <=> 8

Then us stay:

d( A, B) = √[ (3)^2 + (-4)^2+(8)^2]

= √( 9 + 16 + 64)

= √( 25 + 64)

= √(89)
