The area of this rectangle is at most 400 square centimeters. Write and solve an inequality to represent the possible values for the height, h, for this triangle.

could you reply to this with the question so i can ?

6/20

step-by-step explanation:

answer: c

(2, -4)

goes 7 to the

(9, 4)

easy

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)
