Barry is building a fence around rround his bacyard. The backyard is in the shape of a rectangle and the longest side of the yard is 20 meteers. The fence will have a perimer of 60 meters. How many meters long is the short side of the backyrad

10m

Step-by-step explanation:

Recall that the perimeter of a rectangle

= (2 x Long Side) + (2 x Short Side)

we are given that each of the long side = 20m and the perimeter is 60m

substituting these into the equation,

60 = (2 x 20) + (2 x Short Side)

60 = 40 + (2 x Short Side) (subtract 40 from both sides)

60-40 = (2 x Short Side)

(2 x Short Side) = 20 (divide both sides by 2)

Short Side = 20 / 2 = 10m

Sorry if this is wrong, but I didn't quite understand your wording. I'll answer the best I can!

Step-by-step explanation:

2 x (L + W)

2 x (20 + 10)

2 x 30

60

The answer is 10 meters.
