Question

The length of a rectangle is 20 cm more than its breadth . If the perimeter is 100 cm .Finf the dimension of rectangle and area of rectangle .​

Answer 1

Answer:

15 and 35 cm

Step-by-step explanation:

Let the breadth be x.

therefore,length=x+20.

p=100cm

2(x+20+x)=100

4x+40=100

4x=100-40

x=60/4

x=15

therefore,breadth=15cm and length =15+20=35cm.

Answer 2

Answer:

Step-by-step explanation:

perimeter of a square is = 4s

105 = 4s⇒ s= 105/4 = 26.25

area = s² = 26.25²= 689.0625
