<span> If it is parallel to the hypotenuse, then the hypotenuse is twice as long. So h = 8x 
Then the legs will be (8x)/sqr(2). Since the triangle is a 45-45-90 

So the perimeter = 8x + (8x)/sqr(2)+ (8x)/sqr(2) 
=8x+ 16x/sqr(2) 
=8x+ 8xsqr2 

2)if the midsegment Is parallel to a leg, then each leg = 8x and the hypotenuse = 8x sqr2 

Then the perimeter is 8x + 8x + 8xsqr2 
= 16x+ 8xsqr2

amber wants to put tile on the back special for kitchen counter she will need 36 square feet of tile.she will use basic tile tha
Komok [63]

Answer: Amber use 30 feet of basic tiles and 6 feet of decorative tiles.


Step-by-step explanation:

Let x be the foot  of basic tiles and y be the foot of decorative tiles.

Now, according to the question, we have the following equations

x+y=36\\y=36-x\ .......(1)\\\\8x+20y=36\times10\\2x+5y=90.......(2)\ \ \ [\text{divide equation by 4}]

Put y=36-x in (2), we get

2x+5(36-x)=90\\\Rightarrow2x+180-5x=90\\\Rightarrow-3x=-90\\\Rightarrow\ x=30\\\\\Rightarrow\ y=36-30=6

Hence, Amber use 30 feet of basic tiles and 6 feet of decorative tiles.

11cm by 6 cm rectangle
puteri [66]

Answer:

Question unclear.

If the question was about the perimeter of the rectangle, it is calculated as:

= (Length * 2) + (Height * 2)

= (11 * 2) + (6 * 2)

= 22 + 12

= 34 cm

If the question was bout Area, the area is:

= Length * width

= 11 * 6

= 66 cm²
