Question

.The perimeter of a rectangular park is 1000 m. Its length is 20m more than its breadth. What are the length and breadth of the park ?

Answer 1

Step-by-step explanation:

Perimeter of rectangle =1000m

=2(l+b)

Let breadth be b

length =20+b

1000=2[(20+b+b)]

1000=2×(20+2b)

1000=40+4b

1000-40=4b

960=4b

960÷4=240cm=b

Breadth=240cm

Length=20+b

20+240=260cm
