You can find the perimeter of a pentagon by its vertices or by using an unit circle
Answer:
The speed of the cyclist is 10 miles per hour .
Step-by-step explanation:
Given as :
The distance cover by cyclist =
= 20 miles
The distance cover by biker =
= 6 miles
The speed of biker =
= s mph
The speed of cyclist =
= 7 + s mph
The time taken by both cyclist and biker = t hour
Now. Distance = Speed × Time
So,
=
× t
Or, 20 = s × t
Or, t =
.....1
And ,
=
× t
or, 6 = s t
Or, t =
....2
From Eq 1 and 2
I.e
=
Or, 20 s = 6 ( 7 + s )
Or, 20 s - 6 s = 42
Or, 14 s = 42
∴ s = 
I,e s = 3 miles per hour
So, The speed of biker =
= s = 3 miles per hour
And The speed of cyclist =
= 7 + s = 7 + 3= 10 miles per hour
Hence The speed of the cyclist is 10 miles per hour . Answer
1 yard=3 feet
4yards= 4•3= 12 feet
Perimeter of a square = 4•side = 12 so side of the square is 3 feet
Area of square = 3•3=9 Square feet
