38. geometry the perimeter of the square is equal
to the perimeter of the triangle. the sides of the
triangle are equal in length.
a. estimate without doing any calculations,
estimate which figure has the greater side
length. explain your choice.
b. what is the side length of each figure?
c. what is the perimeter of each figure?
5x - 3

answer: answer

step-by-step explanation:

b

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)
