Answer:
Step-by-step explanation:
From the given rectangle,
Length of the rectangle = 5 cm
Width of the rectangle = 10 cm
Ratio of length : width = 1 : 2
Perimeter of the rectangle = 2(l + b)= 150 cm
l + b = 75 -----(1)
Since, l : b = 1 : 2
b = 2l ------(2)
From equations (1) and (2),
l + 2l = 75
3l = 75
l = 25 m
Width 'b' = 2(25) = 50 m
Now we have to draw a rectangle with a scale = 25 : 2
Therefore, Scale factor = 
l = 2 cm
Similarly,
w = 4 cm
Now we can draw a rectangle with length = 2 cm and width = 4 cm.
Answer:
This is an equilateral triangle so it must also be equiangular. A triangle must have 180 degrees and has three angles so 180/3 = 60. Each angle is 60 degrees.

Answer:
TILE SIZES
Contemporary tiles are available in a variety of colors, styles, tile sizes, and shapes, which allows you to create a truly personalized space. Tile sizes are dependent on materials and intended uses, and they have increased dramatically over the years. But while there are some standard tile sizes, there are also a lot of manufacturers that make tiles in sizes specific to their in-house designs. Producers offer an enormous variety of products from very small 0.5” x 0.5” mosaic to large 24” x 24” tiles to suit in any house design and satisfy any customer needs.

Answer:
X=10, Y=20,Z=80
Step-by-step explanation:
We are given that the numbers X,Y and Z are in the ratio 1:2:8
Let the numbers be:
X=x
Y=2x
Z=8x
Now we are given that 40 is subtracted from Z such that the numbers X,Y,Z-40 form a geometric sequence.
that means x,2x,8x-40 forms a geometric sequence.
Also if a,b,c are in geometric progression then they have same common ratio.
i.e. 
Hence, the number X =10
Y=2×10=20
Z=8×10=80
