Question

The perimeter of a rectangle is 170cm .If the length of the rectangle is 45cm,find its breadth . Also find the area of rectangle.​

Answer 1

Answer:

Breadth of the rectangle is 40 cm

Area of the rectangle is 1800 cm²

Given data :

Perimeter = 170 cm

Length = 45 cm

Let,the breadh = x cm

So,

2×(x+45) = 170

2x + 90 = 170

2x = 80

x = 40

So, breadth = 40 cm (answer)

Area = (40×45) = 1800 cm² (answer)

Answer 2

Answer: breath is 40 cm

Step-by-step explanation:

given ,

perimeter=170cm

Length=45cm

Let breadth be 'b'

Perimeter= 2(length + breadth)

=> 170=2(45+b)

=> 170/2=45+b

=> 85-45=b

=> 40=b

Area= l×b = 45×40 = 1800 km square
