If ABCD is a square with one side equal to 10 cm what is the length of BD?
2 answers:
Answer/Step-by-step explanation:
Square = 4 equal sides
1 side = 10 cm
So,
A+B+D+C = 10+10+10+10
so it equals 40
But we arfe looking for half of it or adding of the sides,
B+D
10 + 10 = 20
<h2><u>
Answer = 20 cm </u></h2>
You could have also done it by :
The whole thing is 40, and a square has 4 sides. We are looking at 2 sides which is half so ,
40/2 = 20 cm
<h2><u>
Answer: 20 cm</u></h2>
Answer:
20
Step-by-step explanation:
10+10+10+10=40

Answer:
A = 63.59
C = 28.26
Step-by-step explanation:
r = 4.5
Area of a circle:
A = πr²
A = 3.14(4.5²)
A = 3.14(20.25)
A = 63.59
Circumference:
C = 2πr
C = 2(3.14)(4.5)
C = 28.26
X^5 would be the answer i think.
