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
Answer:
A
Step-by-step explanation:
2 and 4 are on opposite sides of the transversal but both on the inside of the parallel lines. This makes them alternate interior angles, which are congruent.

Answer:
96 cm²
Step-by-step explanation:
The surface area of a pyramid is the sum of the base area and the area of the four triangular faces. Using the formulas for each of these, a simplified formula can be written.
A = s(s +2h)
where s is the side length of the square base, and h is the slant height of a triangular face.
__
For the given dimensions, s=4 cm, h=10 cm, the surface area is ...
A = (4 cm)(4 cm +2×10 cm) = (4)(24) cm²
A = 96 cm²
The surface area of the pyramid is 96 square centimeters.
