Answer:
......
Step-by-step explanation:
Length of diagonal of the rectangle=
√( length) ²+( breadth) ²
=√(20) ²+(12) ²
=√400+144
√544 m
. '. Length of fence= √544 m
Perimeter of the triangle formed by the diagonal of the rectangle =(12+20+√544)
=(32+√544) m
Answer:
m = 28
Step-by-step explanation:
70 × 2 = 5m
140 = 5m
28 = m

Answer:

Step-by-step explanation:
step 1
Find the diameter of the circle
the formula to calculate the distance between two points is equal to

substitute the values




The radius is half the diameter
so

step 2
Find the center of the circle
the center of the circle is the midpoint between the endpoints of the diameter
so
The center is


step 3
Find the equation of the circle
The equation of the circle is

substitute the values


The answer would be 19.87
7.2*12*.23= 19.872
Because two is lower then 5 we could round to 19.87
