Answer: Top box : 10 Ft. , Side box: 21 Ft. , Area: 510 Ft^2, Perimeter: 98 Ft.

Explanation:

- Think about it as two shapes. A smaller rectangle that the sheep is in and a larger one with the rest of the pen. Doing this visually will help.

Top box:

20-10 = 10

- We minus 10 feet from 200 because we are dealing with the 'smaller' shape first, to find the length of its missing side we must subtract the known lengths; we removed the excess.

Side box:

28-9=21

- We do this because 28 Ft was a whole length from end to end when we only need the bigger shape, hence we remove the excess which is 9 Ft.

Area:

-Now we know all our lengths, deal with the two self-allocated 'shapes' as you would normally.

10 x 9 = 90. (Smaller shape.)

20 x 21 = 420. (Larger shape.)

- Then we add them to find the area of the WHOLE shape combined.

90 + 420 = 410 FT²

Perimeter:

- Once again, we know all our lengths and simply add them all together.

10 + 28 + 20 + 21 + 10 + 9 = 98 FT

If this helped, consider dropping a thanks ! Have a good day !

Answer:

perimeter= 96feet

area= 470 feet ^2

Explanation:

to find the perimeter u add all the sides together

top missing side= 10feet

right missing side= 19feet

perimeter= 28+20+10+9+10+19

perimeter= 96 feet

area= 20×19=380

9×10=90

area=380+90

area=470 feet^2
