Given the rectangular solid, rs = 6, st = 3, and sl = 4. solve for kt.

First thing is that you need to find the diagonal of the rectangle

but remember is it a horizontal rectangle.

So let's start it :)

d= √6²+3²

d= √36+9

d= √54

d= 6.7082

But wait.. we are not done yet

We need to solve KT

we have 6.7082 which is the base and we have SL=4 which is the height

so with this 2 information we can find KT

KT is the hypotenuse because when you draw the line from K to T you'll see that it is the longest line.

Use the hypotenuse formula which is

C = √a²+b²

Now replace C by KT since we are solving for KT instead of C. Got it ?:)

KT= √6.7080²+4²

KT= 7.81

I do it with decimals so it might be little bit confusing to you but I think you can solve that different ways :)

Well I hope that's help and if not I am so sorry.

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
