Any help please I appreciate it thank you

Answer:

20 feet

Step-by-step explanation:

Parimeter is how far you would walk if you made a lap around the shape, walking on the edge lines like a balance beam.

To find perimeter, we need to add up all the sides.

Because it's a square each side has the same length.

There are 4 sides.

5 x 4 = 20

or 5 + 5 + 5 + 5 = 20

The perimeter is 20 feet

igor_vitrenko [27]

The error Giovanna made in her calculation is multiplying 7 by 2 and adding with 5/8(step 3)

<h3>Fraction</h3>

Her calculation:

  • 7 (2 and StartFraction 5 over 8 EndFraction): 7(2 5/8)

  • 7 (2 + StartFraction 5 over 8 EndFraction): 7(2 + 5/8)

  • 14 + StartFraction 5 over 8 EndFraction: 14 + 5/8

  • 14 and StartFraction 5 over 8 EndFraction: 14 5/8

Her error was multiplying 7 by 2 and adding with 5/8(step 3)

Correct calculation:

7(2 + 5/8)

= 14 + 35/8

= (112+35) /8

= 147/8

= 18 3/8
