Question

The perimeter of a rectangle is equal to that of a square with side 13m . If the rectangle is 16 m long, what is its breadth ?

Answer 1

Answer:

Step-by-step explanation:

Perimeter of square=2*(13+13)

52

ATQ,

Perimeter of rectangle =52

Length-16

52=2(16+breadth)

16+breadth=52/2

Breadth=26 - 16

Breadth=10

Answer 2

Answer:

It is clear that

Perimeter of rectangle = Perimeter of square

Side = 13 m

Perimeter of square = 4×side

= (4×13) m

= 52 m

Thus, Perimeter of rectangle = 52 m

Let breadth be b.

2(16+b) =52

=>32+2b=52

=>2b=52-32

=>2b=20

$= > b = \frac{20}{2} \\ = > b = 10$

Hence, breadth = 10 m

Formula used in this question :

Perimeter of rectangle = 2 (Length + breadth )

Perimeter of square = 4× side

Extra Information :

Area of rectangle = Length × breadth

Area of square = Side×Side
