Answer 1

Answer:

7.5

Step-by-step explanation:

5100÷85=60

60÷8=7.5

Answer 2

Step-by-step explanation:

$\frak Given = \begin{cases} &\sf{Cost\ of\ flooring\ per\ square\ meter\ =\ Rs.\ 85.} \\ &\sf{Total\ cost\ of\ flooring\ of\ room\ =\ Rs.\ 5100.} \\ &\sf{Length\ of\ the\ room\ =\ 8m.} \end{cases}$

To find:- We have to find the breadth of the room ?

☯️ To find the breadth of the room, first we have to find the area of the room.

$\frak{\underline{\underline{\dag Area\ of\ the\ room:-}}}$

$\sf : \implies {\dfrac{5100}{85}\ =\ 60m².}$

__________________

$\frak{\underline{\underline{\dag As\ we\ know\ that:-}}}$

$\sf\pink{\underline{Area\ of\ the\ room\ =\ length\ ×\ breadth.}}$

__________________

$\frak{\underline{\underline{\dag By\ substituting\ the\ values,\ we\ get:-}}}$

$\sf : \implies {60\ =\ 8\ ×\ b} \\ \\ \sf : \implies {b\ =\ \cancel \dfrac{60}{8}} \\ \\ \sf : \implies {\purple{\underline{\boxed{\bf 7.5m.}}}}\bigstar$

Hence:-

$\sf \therefore {\underline{The\ required\ breadth\ of\ the\ room\ is\ 7.5m.}}$
