Answer:
4 cm
Step-by-step explanation:
The side of the square will be the average of the two sides of the rectangle with the same perimeter.
Formulas for the perimeters are ...
P = 2(L+W)
P = 4s
Equating these gives ...
4s = 2(L+W)
s = (L +W)/2 . . . . . divide by 4
For the given side lengths, ...
s = (2 cm +6 cm)/2 = (8/2) cm = 4 cm
The length of one side of the square is 4 cm.
Answer:
170
Step-by-step explanation:
20 + (26 - 1)6

Answer:
2 1/6 hours.
Step-by-step explanation:
It walks 1 1/2 miles in 3 1/4 hours.
So it walks 1 mile in (3 1/4 ) / (1 1/2) hours.
= 13/4 / 3/2
= 13/4 * 2/3
= 26/12 hours
= 2 1/6 hours.
