Find the area of the trapezoid. Leave your answer in simplest radical form.
Zanzabum

Answer:

A)94.5 cm

Step-by-step explanation:

height = 9cm

Base 1 = 5cm

Area of a Trapezoid = 1/2 × (b1 + b2)h

h = 9cm

b1 = 5cm

b2 = (9 cm + 5cm + 2cm) = 16cm.

Area of Trapezoid

= 1/2 (5 + 16) × 9

= 1/2 × 21 × 9

= 94.5 cm

Option A is the correct answer

What is the answer for. What is hg = 45g
goldenfox [79]
To solve hg = 45g

Apply Multiplication Property of Equality which is to multiply both sides of the equation with 1/g.
  
  hg (1/g) = 45g (1/g)
               h = 45

Or you can divide both sides with the equation with g.
      
   hg / g = 45g / g

You can cancel g to both sides.
Then, 
               h = 45
