Question

find the dimension of a rectangle if its perimeter is 100 cm and its length is 20 CM more than its breadth. ​

Answer 1

Here is your answer.....

l = 20 cm

perimeter of rectangle = l + b

place the value of perimeter and length...

100 = 20 + b

b = 80 cm

Hence the dimension of rectangle is

Answer 2

Answer:

let the breadth be x

there fore, length = x + 20

p = 100 cm

2(x+20+x) =100

4x + 40 = 100

x = 60/4

x = 15

therefore, breadth = 15 cm

and length = 15 + 20

= 35 cm
