The length of DE=sqrt((1-4)^2+(4-0)^2)=sqrt(3^2+4^2)=5
In principle, a rhombus has four equal sides, so the perimeter is 4*5=20 (units)

However, to ensure there is no typo, it is advisable to calculate separately the length of each and every side.

Three consecutive integers whose sum is -147
suter [353]

Step-by-step explanation:

Let the first integer be x

2nd integer = x + 1

3rd integer = x + 2

x + x + 1 + x + 2 = -147

3x + 3 = -147

3x = -147 - 3

3x = -150

x = -150 ÷ 3

x = -50

The three consecutive integers are

-50, -49, -48

vovangra [49]

Answer:

2: The perimeter of the base is 37 units.

Step-by-step explanation:

1. A = LW = 21 * 16 = 336 units^2     True

2. P = 2(L + W) = 2(21 + 16) = 2(37) = 74 units      False

3. H = 21 units     True

4. SA = 2LW + 2H(L + W) = 2(21)(16) + 2(21)(21 + 16) = 2226 units^2     True
