PLease help me in my maths homework I dont really understand it. Calculate the area of the trapezium CDEF
alexira [117]

Answer:

48

Step-by-step explanation:

first, since its a rectangle, the parallel sides are equal making the top of the rectangle 9cm. the to fins the sides, we do 9+9( because of the sides o the rectangle) which gives us 18. then we need to do 28-18 to find out how much both the other sides of the rectangle are, which is 10. now we divide that by 2 since we want one for each side main the measurements for the rectangle are 9cm by 5 cm. now since to find out the area of aa trapezium, we use the formula   A=1/2(a+b)h which means we add the 2 parallel sides of the rectangle which are 5 and 9. we got the 9 from figuring out the rectangle remember? now 9+5=14. next we times it by the height which will be 6 since 11-5 is 6. we got the 5 from figuring out the rectangle above. now 14x6 is 84. however what about then 1/2 part in the formula?. well, all we do now is divide 84 by 2 which gives us 48

REMEMBER: The formulae for working out the area of a trapezium is 1/2x(a+b)xh

Answer:  The cost of one rose bush is $7 and the cost of one shrub is also $7

Step-by-step explanation:

The situtation can be represented by the systems of the equations.

10x + 4y  =  98   x in this case is the cost of  one rose bushes

9x + 9y =  126     y  is the cost of one shrub.  

Solve the system of equation using the elimination method.

10x +4y = 98

9x + 9y = 126     eliminate the y variable so you will have to multiply 9 on top                                          and -4 down.

9(10x +4) = (98)(9)

-4(9x + 9y) = 126(-4)

You will now have the new two systems of equations

90x +36y = 882

-36x +-36y = -504    Now add the equations

0  + 54x = 378      

        54x = 378

  x= 7

Now we know that the cost of one rose bush is 7 so we will plot it into one of the equations and solve for the cost of one shrub.

90(7) +36y=882

630 +36y = 882

-630            -630

    36y = 252

   y = 7

Check:  10(7) + 4(7)= 98

              70  + 28 = 98

             98= 98  

so one rose bush is actually 7 dollars the same as 1 shrub.
