Question

The perimeter of a rectangular room is 70 m. If its length exceeds its breadth by 5 m, find the dimensions of the rectangular room.

Answer 1

${\huge {\mathfrak {Answer :-}}}$

Let, breadth = x.

So, length = x + 5

Thus, 2 (x + x + 5) = 70

Or, 2x + 5 = 35

Or, 2x = 30

Or, x = 30/2 = 15.

➡️ $<b>Breadth = 15 m and Length = 15 + 5 = 20 m. </b>$

That's it.

Answer 2

Answer:

Let the breadth be xm

Let the length be x+5m

Perimeter of room 70m

According. To question

2(x+x+5)=70

2x+2x+10=70

4x+10=70

4x=70-10

4x=60

X=60/4

X=15

breadth=15m

Length=15+5=20m
