Answer:(a) Co-ordinate rule is  and  

(b) Co-ordinates of B' and C' are  and  respectively.

Step-by-step explanation:

(a)

Here, the co-ordinates of A are translated to A'.

For the co-ordinates A and A',   and  

So, x value of A has shifted to right by 6 units and y value of A has shifted 8 units down.

Hence, the co-ordinate rule that maps ΔABC onto ΔA'B'C' is:

and .

(b)

Using the co-ordinate rule, we can find the co-ordinates of B' and C'.

For B,  and .

So,  of B' is  

And,  of B' is .

Therefore, co-ordinates of B' are .

For C,  and .

So,  of C' is  

And,  of C' is .

Levart [38]

Answer:

20 meters square

Step-by-step explanation:

Surface Area of this square based pyramid =  A  = base area + 4* (face area)

A = (2 *2)  +  4* ( (1/2)*2 * 4) )

A = 4 + 4*(4)

A = 4 + 16 = 20

A = 20 square meters
