Answer:
- perimeter: 16 units
- area: 15 square units
Step-by-step explanation:
The dimensions of the rectangle are 3 by 5 units, so the perimeter is ...
P = 2(W+L) = 2(3+5) = 16 . . . units
__
The area is ...
A = WL = (3)(5) = 15 . . . square units
Juan will jump 40 times in 50 seconds.
The unitary method is a concept wherein a problem is solved first by finding the value of a single unit and then multiplying the single unit value to find the necessary answer.
Here, we are given that
Juan jumps 24 times in 30 seconds
Thus, the number of times he will jump in 1 second is given by-
24/ 30 = 0.8
Thus, he jumps 0.8 times in 1 second
Now, we need to find the number of times he jumps in 50 seconds. We can do so simply by multiplying the number of times he jumps in 1 second by 50.
Thus, number of times he jumps in 50 seconds = 0.8 * 50
= 40
Therefore, Juan jumps 40 times in 50 seconds.
