A person jogged 10 times along the perimeter of a rectangular field at the rate of 12 kilometers per hour for 30 minutes. If fie
balu736 [363]

Answer:

20,000m²

Step-by-step explanation:

If they jog 12 km/h for half an hour, they have covered.

12 X 0.5 = 6km in 10 circuits. Making 1 perimeter

6 / 10 =0.6 km (600 m).

To determine area we need to convert this perimeter to length and width. We know that it is a rectangle, with 2 equal widths and 2 equal lengths, and the length is twice the width.

So L = 2W

Perimeter = 2W + 2L

600 m = 2W + 2(2W)

600 m = 6W

W = 100 m

L = 200 m

Area = 100 X 200 = 20,000 m²

Alexxandr [17]

Answer:

2500 kg/m³

Step-by-step explanation:

Density of a material is the ratio of mass and volume of that material.

The S.I unit for density is grams per centimeters cubed (g/cm³) or kilograms per meter cubed (kg/m³)

Given density as 2.5 g/cm³ , convert to kg/m³

Formula is;

1g/cm³ = 1000 kg/m³

2.5 g/cm³=? cross-multiply

=2.5×1000 = 2500 kg/m³
