find the area of rectangle

[analog flax]

what have you tried so far?

did you try to graph it?

[cunning garden]

i graphed the points P and Q

and dunno what to do next

[analog flax]

ok, so we know that it is a rectangle, means it has to have 4 angles with 90°

means to graph QR, you need to draw a line from Q in a 90° to PQ until you hit the x axis

then if you figured out the length of this line, you should be able to calculate the size of the area

now, my question, is a graphical solution enough for you?

[cunning garden]

the graphical solution is not enough

how can i find the lengh of the sides

of that rectangle

knowing only the points P and Q?

[analog flax]

ok so to figure out the length between P and Q, you can use Pythagoras means a²+b² =c²

if you figure out the point R, you can also find out that length and get your area

i have solved it by myself

thank you for ur help

[analog flax]
