Question

The length of a rectangle is 5cm more than its breadth .the perimeter of the rectangle is 46cm. What is the length and the breadth.(let the breadth of the rectangle be b cm

Answer 1

Answer:

Breadth =9cm and length =14cm

Step-by-step explanation:

Let the breadth be b

And length =(b+5)

ATQ

2(b+5+b)=46

2b+10+2b=46

4b=46-10

b=36/4

b=9

Breadth =b=9cm

Length =b+5=9+5=14cm

Answer 2

Step-by-step explanation:

Length = 5+ b

Breadth = b

Perimeter = 46

Perimeter of a triangle = 2(l+b)

46 = 2( 5+b+b)

46/ 2. = 5+b+b

23. = 5+2b

23 - 5. = 2b

18. = 2b

18/2 = b

9. = b

BREADTH = 9

LENGTH. = b + 5

=. 9 +5

=. 14
