How do I do this? I don’t understand this kind of math! plz help

Step-by-step explanation:

The area of a triangle is

A=hb/2, in this case

A=20(18)/2=180m^2

The are of a rectangle is

A=LW in this case

10x=85

x=85/10

x=8.5in

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
