The area of a rectangular ground is 440 sq. m. Its length is 22 a boy runs for Round around it how much distance will he cover ?
Answers
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
