Question

The length of the room is 2½ times the breadth. The perimeter of the room is 70 m. What are the length and breadth of the room?​

Answer 1

$\huge\underline\mathbb{\red S\pink {O}\purple {L} \blue {UT} \orange {I}\green {ON :}}$

According to the question

Let breadth be x

So length = 5/2. X

Now perimeter of rectangle = 2(l+b)

.

so

70 = 2 × ( X + 5/2 X)

35 = 7x/2

x = 35 × 2/7

x = 10

So breadth = 10m

length = 5/2 × 10 = 25m

Answer 2

Answer:

Let breadth be x

So length = 5/2. X

Now perimeter of rectangle = 2(l+b)

.

so

70 = 2 × ( X + 5/2 X)

35 = 7x/2

x = 35 × 2/7

x = 10

So breadth = 10m

length = 5/2 × 10 = 25m
