Question

in a rectangle of perimeter 1 m, one side is 5cm longer than the other side. find the length of the sides​

Answer 1

Answer:

l=0.275m , b=0.225m

Step-by-step explanation:

2(l+b)=1m  -(i)

l=0.05m+b; -(ii)

2(0.05m +b+b)=1m;

b=0.225m

l=0.275m

Answer 2

Answer:

breadth = 22.5 cm and length = 27.5 cm

Step-by-step explanation:

let breadth = b and length = (b + 5 cm) as given

perimeter of rectangle = 1m = 100 cm

= 2 × ( length + breadth )

= 2 × ( b + 5 + b )

= 2 × ( 2b + 5 )

100 cm = 4b + 10

b = (100 - 10) / 4 = 90/4 cm = 22.5 cm

breadth = 22.5 cm and length = b + 5 = 22.5 + 5 = 27.5 cm
