Answer:
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:
23.32 m to the nearest hundredth.
Step-by-step explanation:
Use the Pythagoras theorem:
The diagonal is the hypotenuse of the right angled triangles formed.
x^2 = 12^2 + 20^2
x^2 = 544
x = 23.32 m.
