Let
the length and
the width. By the ratio of the sides:
Now, we'll find the perimeter p. We'll use the formula below:
The area of a rectangle is
. Then:
Answer:
62.8ft
Step-by-step explanation:
The formula to get the circumference is π × D (π × diameter) You need to multiply the value of π (3.14) by the diameter of this circle (20).
20×3.14= 62.8ft
Answer:
The corresponding pair of sides are in the same ratio.
Step-by-step explanation:
For two triangles to be similar, the theorem that is required is the corresponding sides of the two triangles are in the same ratio.
Now, see the diagram of two triangles given with the question.
The ratios of the corresponding sides are 
If two pairs corresponding sides are in 5 : 4 ratio, then the third pair of corresponding sides will also be in 5 : 4 ratio.
Therefore, the two triangles are similar. (Answer)
Answer:
y-1=5(x-3)
Step-by-step explanation:
y-y1=m(x-x1)
m=5
y-1=5(x-3)
