ABCD is rhombus. DC = 5cm, AC = 6cm. Find the length of BD

BD = 8Cm

Step-by-step explanation:

Given:

DC = 5cm

AC = 6cm.

Find;

BD = ?

Computation:

Rhombus's diagonal bisect each other at 90°

Using Pythagoras theorem

OD =

OD =

OD = 4 CM

So, BD = 2(OD)

BD = 2(4)

BD = 8Cm

There are 10 blocks in a row (section). There are  6 rows (sections).

1.

A. If each block has a value of one, what is the value for a section of blocks?

There are 10 blocks in a section. 10 * 1 = 10

B. What is the total value of all the blocks, write an equation?

There are 6 sections. There are 10 blocks in a section. 6 * 10 * 1 = 60

2.

A. If each block has a value of ten, what is the value for a section of blocks?

There are 10 blocks in a section. 10 * 10 = 100

B. What is the total value of all the blocks, write an equation?

There are 6 sections. There are 10 blocks in a section. 60 * 10 * 10 = 600
