Question

The foot of ladder is 2m from a wall and the top of the ladder is 6m above the ground .calculatebthe lenght of the ladder

Answer 1

Answer:

I am not correct but I tried that is the main thing.

Step-by-step explanation:

given:

the ladders are long c = 6 m

base is a = 2 m

b = height of ladder above ground

b = √ ( c² - a² )

b = √ ( 6² - 2² )

b = √ ( 36 - 4 )

b = √ 32

b = 5.656854249 m

To round a number to a two decimal places, look at the number in the third decimal place.

Leave the second decimal same if the number in the third decimal is less than 5

(this is called rounding down)

Increase the second decimal by 1 if the number in the third decimal is 5 or more

(this is called rounding up)

In this case number in the third decimal is 6 so increase the second decimal by 1:

b = 5.66 m

rounded on two decimal places

Answer 2

Answer:

base 2m

height 6m

ac²=ab²+bc²

Length of Ladder = √40m or 2√10m or 6.32m
