Question

she buys 80cm of white clothe, 60 cm of blue cloth and 2m of pink cloth. find the total length of clothe bought by her​

Answer 1

Answer:

122cm

Step-by-step explanation:

white cloth - 80cm

blue cloth - 60cm

pink cloth - 2cm

Therefore, total length of the cloth bought by her =

80+60+2cm

- 122cm

Answer 2

Analysis:

The purchase of clothes on various colours by her:

$\begin{gathered} \tiny\boxed{\begin{array}{ c |c} \frak{ \pmb{Cloth}}& \rm{ \pmb{Length}}\\ \dfrac{\qquad\qquad}{ \sf White}&\dfrac{\qquad\qquad}{ \sf 80 \: cm}& \\ \dfrac{\qquad\qquad}{ \sf Blue}& \dfrac{\qquad\qquad}{ \sf 60 \:cm}& \\ \dfrac{\qquad\qquad}{ \sf Pink}&\dfrac{\qquad\qquad}{ \sf 2 \: m }& \\ \end{array}}\end{gathered}$

To find:

• The total length of clothes bought by her.

Concept:

‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎Here, we'll be finding the required answer using the concept arithmetic operations. Arithmetic operations are a branch of Mathematics that deals with the study of number system with various properties. As per our question, we will be using addition as we're asked to find the total quantity. The word "total" refers to count or sum up an expression. The arithmetic operator that shall be used is plus (+).

Solution:

For adding any quantities, first we should ensure that they're in same units. We do this to avoid confusions. So, now let's check whether all the given quantities are in same units!

The lengths of white and blue coloured clothes are in "centimetres" whereas, the length of pink coloured cloth is in "metres". Henceforth, it has to be converted into centimetres.

We know that, $\small{\boxed{\sf{1\:m=100\:cm}}}$. So, 2 metres of cloth equals:

$\longrightarrow{ \sf{2 \times 100}} \\ \\ \longrightarrow \underline{ \sf{200 \: cm}}$

$\:$

Now, all the quantities are in same units. So, let's arrange them in descending order!

‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎200 cm, 80 cm, 60 cm

$\:$

Now we shall add these quantities:

$\: \: \: \: \: \: \: \: \: \: \: \begin{gathered} \boxed{\boxed{\begin{array}{} \tiny \blue{\boxed{\sf{1}}} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \sf{2 \: \: \: 0 \: \: \: 0} \\ \sf{\: \: \: \: \: 8 \: \: \: 0}\\ \sf{ \red{ \pmb{ +}} \: \: 6 \: \: \: 0} \\ \red{ \pmb{- - - - - }}\\ \sf{ \blue{ \pmb{3 \: \: \: 4 \: \: \: 0}}}\\ \red { \pmb{ - - - - - }}\end{array}}}\end{gathered}$

By adding we got the sum as 340, which is $\underline\frak{\red{340\:cm}}\rightarrow\sf{Required\:answer}$

$\\ \therefore \underline{ \sf{She \: bought \: \tt{ \pink{ 340 \: cm \: (3.4 \: metres)}} \sf{ \: of \: cloth.}}}$
