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

<h3>
x = 6 ft. long shadow</h3><h3>
</h3>
Step-by-step explanation:
its a ratio and proportion:
<u> 15 ft. tall giraffe </u> = <u> 5 ft. tall bird </u>
18 ft. shadow x shadow
15 (x) = 18 (5)
x = 90 / 15
x = 6 ft. long shadow

Answer:
The expression (2 x 3) + 13 - 1 on simplifying gives 18.
Step-by-step explanation:
Here, the outcome of the expression is 18.
Using at least three operations.
Here, we use three operations Addition = '+' , Subtraction = '-' and
Multiplication = 'X'
Take the number 2 and multiply it with other number 3.
We get 2 x 3 = 6
Take the product, add it with another number 13
So, 6+ 13= 19
Take the resultant and subtract 1 from it.
We get 19 - 1 = 18
⇒The combined expression is (2 x 3) + 13 - 1 = 18
The above expression on simplifying gives 18.
