Answer:

Step-by-step explanation:

So the Dimensions are:

Height: 300cm

Length: 300cm

Width: 2cm

SA = 2(H*L)+2(H*W)+2(L*W)

= 180000 + 1200 + 1200

= 182400 $cm^{2}$ OR 18.24 $m^{2}$

Answer:

182400 cm²

Step-by-step explanation:

At = 2( l×w + l×h + h×w)

= 2(300cm×2cm + 300cm×300cm + 300cm×2cm)

= 2(600cm² + 90000cm² + 600cm²)

= 2×91200cm²

= 182400 cm²

if the breadth of rectangle in one third of it's length and perimeter is 80 cm,find the length and breadth of rectangle

Serhud [2]

Length＝x
Breadth＝1/3x
(x＋1/3x)×2＝80
4/3x×2＝80
8/3x＝80
x＝30
Length＝30
Breadth＝1/3×30＝10

Hope my answer helped u :)

Consider the planes x_1 + x_2 + 3x_3 =4 and x_1 + 2x_2 + 4x_3 = 5 in r3 find parametric equations for the line of intersection o

adoni [48]

You can solve for x and y in terms of z, then let z take on the value of the parameter.

Subtracting the first equation from the second, you get

... x_2 +x_3 = 1

Subtracting that from the first equation gives you

... x_1 +2x_3 = 3

Let x_3 = t. Then your parametric equations are ...

$x_1=3-2t\\x_2=1-t\\x_3=t$
