Step-by-step explanation:
1. 
Base =16 ft and Height = 18 ft
Area of the parallelogram = base × height
                                        =16× 18 square units
                                        = 288 square units
2. 
Base = 9 m and height = 5 m
Area of the parallelogram = base × height
                                         =(9×5) 
                                          =45 
3 .
Height = 4 in and parallel sides are 12 in and 5 in
Area of the  trapezoid =
                              square in.
 square in.
                              = 34 square in.
4.
Height = 2 ft  and parallel sides are 2 ft and 6 ft
Area of the trapezoid =
                                square ft
 square ft
                               = 8 square ft
5.
Diagonals are 6 cm and 9 cm.
Area of the rhombus 
                                 square cm
 square cm
                                = 27 square cm
6. Diagonals are 12 in and 18 in
Area of the rhombus 
                                 square in
 square in
                                = 108 square in
7. Given a desktop in the shape of a parallelogram has a base 30 in. and a height of 40 in 
The area of the desktop is = (30 × 40 ) square in
                                             = 1200 square in
8. Given , a rhombus has one diagonal that is 14 cm and other diagonal 12 cm.
The area of the rhombus =  
 
                                          =84 
9.Given , the base of trapezoid are 24 ft  and 16 ft and height is 12 ft
Area of the trapezoid =
                                     =  square ft
 square ft
                                      = 240 square ft
 
        
        
        
Answer:
48
Step-by-step explanation:
If we know that the max possible score is 100%, and she got 80% for getting 60 marks, we can set it up as a porportion. 
60 * 80 = 4800
4800/100 = 48
 
        
                    
             
        
        
        
Answer: 37 1/3
Step-by-step explanation:
14/1÷3/8=?
Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes
14/1 × 8/3=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
14×8/1×3 = 112/3
This fraction cannot be reduced.
The fraction
112/3
is the same as
112÷3
Convert to a mixed number using
 long division so 
112/3=37 1/3
Therefore:
14/1 ÷ 3/8=37 1/3
 
        
             
        
        
        
Answer:
y = 2
Step-by-step explanation:
The mid segment HJ is half of the third side GK , that is
HJ =  GK , substitute values
 GK , substitute values
2y =  (y + 6) ← multiply both sides by 2 to clear the fraction
 (y + 6) ← multiply both sides by 2 to clear the fraction
4y = y + 6 ( subtract y from both sides )
3y = 6 ( divide both sides by 3 )
y = 2
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Equation
L = a + (n - 1)*d
Givens
L = 55
a = 13
n =8
Solution
55 = 13 + (8 - 1)*d               Combine
55 = 13 + 7d                       Subtract 13 from both sides
55 - 13 = 7d
42 = 7d                               Divide by 7
d = 6
