Question

One for Stephen Hawking!
Thornes park is an existing development.A further site of 2.73 hectares is being offered.
calculate the area of each plot using algebra.
Plot A is twice as large as plot B.
Plot B is 1.2 hectares smaller than plot C.
The site is to be divided into 3 plots.

Answer 1

Let one of the plot become x and form equations for each of three statements you were given.

Answer 2

one of the plots*

Answer 3

of the three*

Answer 4

Let the size of Plot B be x.
I will do the first statement for you and we will see if you can do the second one.
Your first statement says that Plot A is twice the size of Plot B. And you know we just let Plot B equal x. So the statement can be reworded such as this: "Plot A is twice x."
\[PlotA=2x\]

Answer 5

What can you say about Plot C in terms of x. Try reading the 2nd statement over and over again until you get the gist of it.

Answer 6

Plot C is 1.2 hectares bigger than B?

Answer 7

C=B-1.2?

Answer 8

If i let B be X
c=x-1.2?

Answer 9

When do you ever use this stuff in the real world...aggghhhh

Answer 10

c=X + 1.2
I think ive got it?

Answer 11

B = A divide by 2?

Answer 12

or C - 1.2?

Answer 13

A=2X
B=A divide by 2
C=X + 1.2

Answer 14

next step .
(Xx2)+(x/2)+(x+1.2)
????

Answer 15

Taken me ages .
B + (B+1.2)+(2B)=2.73
4B+1.2=2.73
B=(2.73-1.2)/4
B=0.3825
A=0.765
C=1.5825
A+B+C= 2.73
