Question

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

Answer 1

Answer:

Perimeter : 2(l+b)

2×(5+b) = 100cm

10+2b = 100

2b = 100-10 = 90

b = 90/2

Thus the length of breadth = 45cm

Answer 2

Answer:

l=27.5cm

b=22.5cm

Step-by-step explanation:

perimeter of rectangle:2(l+b))=1m=100cm

given that one side is 5cm longer than the other

length (l)= breadth (b) +5cm

p=2(l+b)

100 = 2((b+5)+b)

50=2b+5

50-5=2b

45=2b

b =45/2

b=22.5cm

l=b+5

=22.5+5

l=27.5cm
