Question

The pair of linear equation in two variables formed from the statements are

(a) x + y = 13 , x + y = 9 (b) 2x + y = 13 , x + y = 9

(c) x + y = 13 , 2x + y = 9 (d)None of thes​

Answer 1

Step-by-step explanation:

the given design states is rectangular

so:- opposite side are equal

then:-. X+Y+2=15

X+Y=15-2

X+Y=13

therefore X+Y=13 is the

answer of this question

Answer 2

$\large\underline{\sf{Solution-}}$

Given that,

• Area of 2 bed rooms and one kitchen together is 95 square m.

Dimensions of Bed Room

• Length of room = x m

• Breadth of room = 5 m

So,

Area of 1 room = Length × Breadth = 5x square m

Thus,

Area of 2 Bed rooms = 10x square m

Dimensions of Kitchen

• Length of Kitchen = y m

• Breadth of Kitchen = 5 m

So,

Area of Kitchen = Length × Breadth = 5y

So, According to statement

$\rm :\longmapsto\:10x + 5y = 95$

$\rm :\longmapsto\:5(2x + y) = 95$

$\rm :\longmapsto\:\boxed{\tt{ 2x + y = 19}} - - - (1)$

Also, From figure

$\rm :\longmapsto\:x + 2 + y = 15$

$\rm :\longmapsto\:\boxed{\tt{ x + y = 13 \: }} - - - (2)$

So, Required Linear Equations are

$\begin{gathered}\begin{gathered}\bf\: \rm\implies \:\begin{cases} &\sf{2x + y = 19} \\ \\ &\sf{x + y = 13} \end{cases}\end{gathered}\end{gathered}$

So, Option (d) is correct
