Answer 2

Answer:

Given: length = width+5

Perimeter = 86m

To find: Dimensions of the floor

Step-by-step explanation:

Let length be 'l' and width be 'w'

According to the question,

l=w+5

Perimeter =2(length +breadth)

86=2(w+5+w) (we are writing length as w+5)

86=2(2w+5)

86/2 = 2w+5

43 = 2w+5

43-5 = 2w

38= 2w

38/2 =w

19= w.

Length =w+5

19+5

24.

Therefore, length is 24m and breadth or width is 19m
