Answer:

Boy will cover a distance of 84 cm.

Step-by-step explanation:

Given the area of a rectangle having length 22 cm is 440.

Then breadth of the rectangle will be 440÷22 =20 cm.

So length is 22 cm and breadth is 20 cm.

Then perimeter of the rectangle is = 2(L+B)

=2(22+20)

=2×42

=84 cm.

So the perimeter is 84 cm.

Answer:

84m

Given:

Area of rectangular ground = 440m²

Length of the ground = 22m

Step-by-step explanation:

► To find breadth of the ground

Let the length be 'l'

Let the breadth be 'b'

  • Area of rectangle = l × b

According to the Question:

l × b = area

22 × b = 440

  • By transposing 22 from L.H.S. to R.H.S, the sign of operation changes from multiplication to division, and we get:

⇒ b = 440/22  ⇔  20

∴ Breadth of Ground = 20m

To find the distance covered by the boy

Distance covered by the boy  =  Perimeter of the rectangular ground

  • Perimeter of rectangle = 2(l + b)

→ 2 × (22 + 20)

⇒ 2 × 42  =  84

⇒⇒ Perimeter of Ground = 84m

∴ Distance covered by the boy = 84m
