Question

Riyadh runs around a rectangular park of length 75 cm breadth 40 cm. How much distance did she covers in 4 rounds

Answer 1

around = Perimeter

l = 75cm

b = 40cm

Perimeter = 2 (l +b)

= 2 (75 + 40)

= 2 × 115

= 230cm

4 times = 4 × 230

= 920cm

Answer 2

Answer:

Ans. 920 cm

Step-by-step explanation:

Length of rectangular park = 75 cm

Breadth of rectangular park = 40 cm

In 1 round distance covered = 2 (length + breadth)

= 2 ( 75+40 )

= 2×115

= 230 cm

In 4 round distance covered = 230 × 4 cm

= 920 cm
