Question

A rectangular field is 40 m long and 30 m wide . If a girl runs around the field twice , find the distance covered by her.

Answer 1

Answer:

280m

Step-by-step explanation:

If rectangle perimeter formula is (length + breadth)×2 then:

40+30×2 = 140= 70 × 2

If the girl went twice then

140

×2= 280m

Answer 2

The total distance covered by her is 280 m

Step-by-step explanation:

Length of rectangular field = 40 m

Breadth of rectangular field = 30 m

Perimeter of rectangular field = 2(l+b)

Perimeter of rectangular field = 2(40+30)

Perimeter of rectangular field =140 m

Distance covered in 1 round = 140 m

Distance covered in 2 rounds = $140 \times 2 = 280 m$

Hence The total distance covered by her is 280 m
