Ayden had a goal of finishing painting at least 80\%80%80, percent of the 500500500 square meters of a house's walls by today. He actually finished painting 415415415 square meters today. Did Ayden meet his goal? Why? , Ayden painted square meters than his goal.

Answer 1

Answer: Yes,
`15\ m^2`

Explanation:

Given

The surface area of the house
`A=500\ m^2`

Ayden aims to finish 80% of the painting

The actual painting done by him is
`A_c=415\ m^2`

Now 80% of the total is

`\Rightarrow A'=500* (80)/(100)=400\ m^2`

Clearly, actual painting done is more than 80% of the painting

`\therefore` Ayden meet his goal

`\Rightarrow A_c-A'=415-400=15\ m^2`

He painted
`15\ m^2` more than his target
