Question

Julie build a kennel whose base is in the shape of a rectangle af dimensions 100 cm by 40 cm. She wants to put a fence around it. Find the length of fence required in metres.​

Answer 1

Answer:

280 cm

Step-by-step explanation:

Lenght of the fence required = Perimeter of the rectangle

= 2(l+b) = 2(100+40)cm = 280 cm

Answer 2

Answer:

2.8 metres

Step-by-step explanation:

The fence length = Perimeter of the rectangle

Perimeter = 2*(l+b)

= 2*(100+40)

= 2*140

= 280 cm

Since, 1 m = 100 cm

280 cm= 2.8 m

Therefore, length of the fence required is 2.8 metres...
