l(AB)=10CM
FIND l(CD) AND l(AC)
Answers
Step-by-step explanation:
all sides are equal.in square
ab = 10
ac = 10
ac = 14.213
Answer: CD = 10 cm
and, AC = 2√5 cm
Step-by-step explanation:
Since,
All the sides of a square are equal, we have:
AB=10CM
AB=BC=CD=DA=10 CM
Now, for AC _______________
=> Diagonal = √2 x side l Rough Work
=> AC = √2 x 10 l 2 l___ 20___
=> AC = √20 l 2 l___10___
=> AC = 2√5 l 5
l _____= 2√5____
