I really need help on these two questions. its my last two.

10. 200 sq.in

11. 56 sq.in

Step-by-step explanation:

10.

area = 16×2 + 12×10 + 1/2 × 8 ×12

= 32+ 120 + 48

= 200

11.

area= 1/2 ×3 × 4+ 1/2×5×4 + 8×5

= 6+ 10 + 40

=56 sq.in

I'm not sure you know but has a problem showing all images so at this point your question is and unanswerable +5 bullseye with letters.

so their by for i have no explanation to give since i already stated it.

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)
