Which equation should be used to find the area of the triangle below? Group of answer choices

5×5 1/2×2 1/2=62 2/5 square inches

5×2 2/5×1/2=6 square inches

5 1/2×2 1/2×12=6 6/25 square inches

5 1/2×5×1/2=1/3 square inches

5×2 2/5×1/2=6 square inches

Step-by-step explanation:

A = ½bh

A = ½(2⅖)(5)

A = 6 in²

answer: #1 ads up by 8 and i don't know #2

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)
