Question

when the approximate length of a ruler is 16cm what will be its length when it is broken in to three pieces and one of the piece is 5.60cm and the other two pieces are of equal length. find the length of the other two piece?​

Answer 1

Answer:

5.2 , 5.2 cm approx

length of that two pieces

Answer 2

$\overline{\underline{\boxed{\sf GIVEN \darr}}}$

The approximate length of a ruler is 16cm what will be its length when it is broken in to three pieces and one of the piece is 5.60cm and the other two pieces are of equal length. find the length of the other two piece?

$\overline{\underline{\boxed{\sf HOW \: TO \: DO \darr}}}$

Step 1 : We will assume the two sides by picking any variable of your wish

Step 2 : We will add all the three sides to get 16 cm

Step 3 : Finally we will put the value in place of the variable to get the other two sides

$\overline{\underline{\boxed{\sf LET \: US \: ASSUME \darr}}}$

It is given that the other two side are of equal length

• The other two sides be x

2nd Side = x

3rd Side = x

It means that 2nd side = 3rd Side = x

$\overline{\underline{\boxed{\sf SOLUTION \darr}}}$

Given that :

Length of the scale = 16 cm

1st side = 5.60 cm

2nd Side = x

3rd Side = x

So,

All the three side = the total length

• 1st side + 2nd side + 3rd side = 16 cm

• 5.60 cm + x + x = 16 cm

Transposing 5.60 cm to left hand side we get

• x + x = 16 cm - 5.60 cm

• 2x = 10.40 cm

• x = 10.40 cm/2

• x = 5.2 cm

So,

2nd side = x

∴ 2nd side = 5.2 cm

3rd side = x

∴ 3rd side = 5.2 cm

Hence, both 2nd side and 3rd side is 5.2 cm
