Question

If ABCD is a square with one side equal to 10 cm what is the length of BD?

Answer 1

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

Answer = 20 cm

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

Answer: 20 cm

Answer 2

Answer:

20

Step-by-step explanation:

10+10+10+10=40

40/2=20
