Answer:

D) b = \frac{S-2ac}{2a + 2c}

Step-by-step explanation:

First, move all the terms that do not include b to the left side with S:

S = 2ab + 2bc + 2ac

S - 2ac = 2ab + 2bc

Now, factor out 2b from the right side:

S - 2ac = 2b(a + c)

Divide both sides by 2(a + c):

b = \frac{S-2ac}{2(a + c)}

Finally, multiply out the denominator:

b = \frac{S-2ac}{2a + 2c}

How many centimeters are in 8 feet, given that 1 in. 2.54 cm.​

Answer:

243.84

Step-by-step explanation:

We change feet to inches, and inches to cm.

1 ft = 12 in.

1 in. = 2.54 cm

8 ft * (12 in.)/(1 ft) * (2.54 cm)/(1 in.) = 243.84 cm

8 ft = 243.84 cm

Help me with a. b. c. I need help
hammer [34]

Answer:

a) Perimeter = 20.5 Inches

   Area is 15 Sq Inches

b) Perimeter is 61.4 Cms

    Area is 210 Sq cm

c) Perimeter is 22 yards

   Area is 21 Sq Yards

Step-by-step explanation:

a) Perimeter = sum of all the sides

= 8+7.5+5

=20.5

Perimeter = 20.5 Inches

Area of Triangle =\frac{1}{2} \times height \times Base

Base = 7.5 In

Height = 4 In

A = \frac{1}{2} \times 4 \times 7.5

A = 2 \times 7.5

A = 15

Hence Area is 15 Sq Inches

b)  Perimeter = Sum of all the sides

P=13+23+13.4+12

P=61.4

Perimeter is 61.4 Cms

Area of trapezium = \frac{1}{2} \times height  \times (sum \ of \ parallel \ sides)

A= \frac{1}{2} \times 12 \times (12+23)

A= 6 \times 25

A=210

Area is 210 Sq cm

c) Perimeter = Sum of all the sides

P = 7+4+7+4 ( as Opposite sides are equal in a parallelogram

P = 22

Perimeter is 22 yards

Area of a parallelogram = base \times height

A= 7 \times 3

A = 21

Area is 21 Sq Yards
