Answer 1

Answer:

On each step distance would be 12+5=17

Since there are 4 steps 4 multiplied by 17= 68.

Answer 2

Given: An ant is scramping on the stairs

There are '4' stairs and each stair has a width of 12 cm and a height of 5 cm.

To Find: distance travelled by the art to scramp the stairs

Displacement

Solution:

Distance travelled in one step  =  12 + 5   =  17 cm

Disatnce travelled in 4 steps = 4 * 17 = 68 cm

distance travelled by the art to scramp the stairs = 68 cm

Horizontal Distance = 12 * 4 = 48 cm

Vertical Distance = 5 * 4 = 20 cm

Displacement = √48² + 20²

= 4√12² + 5²

= 4(13)

= 52 cm

distance travelled by the art to scramp the stairs = 68 cm

Displacement = 52 cm
