For the Octopus we can use the number to find the total number of limbs. We may also use numbers to find the swimming speed of the octopus.

For the second diagram given to us we can use numbers to find the volumes of the two containers and see if transferring any liquid from the first container to the second one will lead to spilling due to volume mismatch or not.

For the last diagram we can use numbers to find the height, width, breadth, in other words, dimensions of the scooter. We may also use numbers to find the speed of the scooter.

The perimeter of a playing field for a certain sport is 174 ft. The field is a rectangle, and the length is 45 ft longer than th
Leno4ka [110]

Answer:

21 ft by 66 ft

Step-by-step explanation:

From the question,

P = 2(L+W)............... Equation 1

Where P = Perimeter of the playing Field, L = Length of the playing Field, W = width of the playing Field.

If the Length of the Field is 45 ft longer than the width,

L = 45+W............ Equation 2

Substitute Equation 2 into equation 1

P = 2(45+W+W)

P = 90+4W............. Equation 3

Given: P = 174 ft.

Substitute into equation 3

174 = 90+4W

4W = 174-90

4W = 84

W = 84/4

W = 21 ft.

Substituting the value of W into equation 2

L = 45+21

L = 66 ft.

Hence the dimensions of the playing field is 21 ft by 66 ft
