nah it's a square with sides=1, an easy graph on the 2d plane(x,y axis) will let u c..(u got 2 sets of points 1 above each other(A above D and B above C), and 2 sets of points 1 next to each other(A is next to B, C is next to D), all of them with distance=1 m and perpendicular so yea)...

a square is always a rectagle and a rhombus(whereas the 2 latter are not always a square), so i guess it's a trick question and the answer is D :S tho it's weird..

i'd hit ur teacher in the head...

do correct me if i'm wrong any1

" B "

Two sides shorter

Two sides longer

Making it a rectangle

In order for it to be a square and a rhombus, there should be 4 equal sides ( same length ).

A(5,10) = rectangle ( x = 5, y = 10 )

B(4,10) = rectangle ( x = 4, y = 10 )

C(4,9) = rectangle ( x = 4, y = 9 )

D(5,9) = rectangle ( x = 5, y = 9 )

answer D all three

Plot the points, and see what shape is there.

remember that a square is a rectangle and a rhombus

Graph the cooedibates and check

It is a square (A)

Verification:

AB=BC=CD=DA = 1 :all sides are equal

this may well be a simultaneous equation concern. enable x: grownup, y: toddlers x+y=one hundred (a million) 50x+30y=3180 (2) could desire to clean up the above 2 equations. Rearranging the 1st one: x=one hundred-y (3) changing equation (3) in (2): 50(one hundred-y)+30y=3180 (4) Simplifying (4) supplies: 5000-50y+30y=3180 and it is comparable to -20y=-1820 y=-1820/-20=ninety one changing y in (3) supplies x=one hundred-ninety one=9 hence, no. of grownup is 9 and no. of youngsters is ninety one.
