Hi I'm 9 years old my name is Emma can

Answer 1

Given:

Perimeter = 40 feet,

The measure of the four sides is 11 feet, g, 11 feet, and g.

We know that the perimeter = the sum of the four sides.

`\text{perimeter =11+g+11+g}`

Replace perimeter =40, we get

`\text{40=11+g+11+g}`

Adding 11 and 11, we get

`\text{40=11+11+g+g}`

`\text{40=22+g+g}`
