PLEEEAAAAAASE HELP!<br>What is the answer to this question?<br><br>​
IrinaVladis [17]

Answer:

  • 23 units

Step-by-step explanation:

<em>Perimeter is the sum of side lengths</em>

<u>Let's find the sides first</u>

  • AB = √(-2- 2)² + (-4+1)² = 5
  • BC = (2 - (-1)) = 3
  • CD = √(-1- 2)²+(5-2)² = √18 = 3√2 = 4.24
  • DE = √(-4 -(-1))²+(2-5)²= √18 = 3√2 = 4.24
  • AE = √(-4-(-2)²+(2-(-4))²=√40= 2√10 = 6.32

<u>Perimeter is</u>

  • P = 5 + 3 + 4.24 + 4.24 + 6.32 = 22.8 ≈ 23 rounded to the nearest whole number

a. How wide must a wall footing be if the load is 9,500 pounds per foot of wall length, and the footing rests on a sandy gravel?
Phantasy [73]

Answer:

a) 38"

b) L = 5.7'

Step-by-step explanation:

a) Given

P = 9,500 lb/ft

Thick = 18"

We assume an allowable bearing pressure of σ = 3000 lb/sf

If Stress = Force / Area

σ = P/A

Solving for area

A = P/σ  ⇒  A = 9,500 lb/ft/3000 lb/sf

⇒  A = 3.167 sf,  or  3.167 ft wide, per foot of length.

⇒  A = 38" wide

We can see the pic 1 in order to understand the answer.

b) Given

P = 65,000 pounds = 65,000 lb

Thick = 18" = 1.5'

We assume an allowable bearing pressure of σ = 2000 lb/sf

If Stress = Force / Area

σ = P/A

Solving for area

A = P/σ  ⇒  A = 65,000 lb/2000 lb/sf

⇒  A = 32.5 sf

then A = L²  ⇒  L = √A = √(32.5 sf) = 5.7 ft

Finally L = 5.7'

We can see the pic 2 in order to understand the answer.
