Question

@Will.H

Answer 1

these formed triangles are right triangles ,yes ?
hope you know formula for area of a triangle
with these is solved your exercise bc. the lateral side will be the height of triangle and you know that the lateral sides of a rectangle are congruent

do you understand it ?

Answer 2

and yes sure these opposite parallel longer sides of a rectangle are the same congruent too

Answer 3

yes there right triangles... everything else sounds like some alien demonic talk lol

Answer 4

so these formed triangles has congruent base and congruent height so from these result areas equals - yes ?

Answer 5

Area = 0.5 * b * h
We need to.find the length of the base and the height.
Base = sqrt (Y2-Y1)^2 + (X2-X1)^2
(0,b) (0,0)
Base = sqrt (0-b)^2 + (0-0)^2
Base = sqrt -b^2
Base = sqrt b^2

Height (0,b) (a,b)
Height = sqrt (Y2-Y1)^2 + (X2-X1)^2
Height = sqrt(b - b)^2 + (a -0)^2
Height = sqrt a^2

Now substitute
Area = 0.5 * sqrt b^2 * sqrt a^2

How are you supposed to get a value for that??

Answer 6

yes area is equal

Answer 7

will is that for me?

Answer 8

Lol yeah

Answer 9

Oh they said enter an expression. So mine is right

Answer 10

it looks wierd lol... what do i put as anwser lol

Answer 11

Area is 0.5 * Sqrt(b)^2 * sqrt(a)^2

Answer 12

You don't have to put the parentheses

Answer 13

And instead of 0.5 it can also.be 1/2

Answer 14

Andrew do u agree

Answer 15

but why you dont squarrooted these a^2 and b^2 and so will result

(ab)/2 for area of a triangle

yes ?

Answer 16

See that's the problem it can be formed in many ways. I don't know which one they want

Answer 17

so this is the anwser?

Answer 18

and this (ab9/2 will result for area of every two triangles

Answer 19

sorry (ab)/2 wan being there

Answer 20

will yes ?

Answer 21

It can also work that way Yeah. And you can remove.the parentheses. Have it any way u like Devon. BTW jhony in.ur form.what would be the full expression

Answer 22

Andrew?

Answer 23

jhonny write what you think the anwser is

Answer 24

He left

Answer 25

ill just use yours

Answer 26

Øk

Answer 27

ok 1 question left
