Question

In a Rectangle of perimeter 30cm) Length
is 1 cm More than the Breadth what
are the
Length of the sides.​

Answer 1

Answer:

Given that the side of square is p cm and Pis one third of breath of rectangle and length is 1 cm more the breadth rectangle

Then breadth =3p and length =3p+1

So area of rectangle =3p(3p+1)=3p(3p+1)=9p

2

+3p

If a square of side p cut in to rectangle

Then the area of square =p

2

So Remaining area left of rectangle after cutting of square =9p

2

+3p+p

2

=(8p

2

+3p) sq cm

Answer 2

Answer:

Length= 8cm and Breath = 7cm

Step-by-step explanation:

perimeter = 30cm and length = 1cm + breath

30 = 2× ( l + b)

30/2 = 1+ b+ b

15 = 1+ 2b

14 = 2b

7 = b

then b +1 = l

i.e., length = 7cm + 1cm = 8cm
