Answer:

Perimeter: 47.2 in Area: 49² in

Explanation:

First to find the perimeter you have to add 17.2 with 10, 2, 3, 3, 7, and 5. You get 47.2 in as your perimeter. To get the area, first you multiply 10 by 14 and you get 140. Now divide that by 2 to get 70. Now multiply 7 by 3 to get 21. Subtract 21 from 70 to get 49² as your answer

Answer:

Perimeter= 44.2 inches

Area= 70 inches squared

Explanation:

Perimeter- Add all your sides together (10+ 17.2+2+3+7+5=44.2)

Area- 1/2bh (b=base, h=height)

Your base is the bottom of the triangle, so 2+7+5=14.

14 is your base

Your height is the 10

1/2 *14*10

1/2 of 14 is 7

7*10= 70

Don't forget to write inches squared or it will be wrong

Hope this helps :)
