Question

formula for finding lenght ,if primeter is given but width not gien​

Answer 1

Let the length be x and breath be x, let be perimeter 100
Perimeter = x+x
100=2x
100/2=x
50 =x

Answer 2

ANSWER

Suppose the perimeter is 100 and width is 10. then take the value of length as x

perimeter= 2(length+width)

100= 2(x+10)

100-10=2x

90=2x

90/2=x

45=x

therefore the length is 45
