Question

if the perimeter of a rectangular Park is 840 M and its length is 280 M what will be its breadth?

Answer 1

2(l+b)=840m

2(280+X)=840

560+2x=840

2x=280M

X=140M

Answer 2

140 metres is the correct answer

Step-by-step explanation:

As we know,

perimeter of rectangle = 2(l+b)

where l is length and b is breadth .

ATQ,

2(280+b)=840 m

280+b= 420m

b= 420-280

b= 140m

hence the bradth will be 140m.
