Answer:
660 length+924width times 2=3168 m
Step-by-step explanation:
Answer:
19.24 cm
Step-by-step explanation:
Square the outsides of the triangle. 8 squared is 64 and 5 squared is 25.
A^2+B^2=C^2
c^2 is always the diagonal line.
a^2=25
c^2=64
Subtract 25 from 64 to find b^2
64-25= 39
Add all three together to get your perimeter.
The square root of 64 is 8, the square root of 25 is 5 and the square root of 39 is 6.24. Add 8, 5 and 6.24 together and you get the perimeter.
5+8+6.24= 19.24
Answer:
bottom: 12 x 12 = 144
1st triangle: (12 x 8)/2 = 48
2nd triangle: 48
3rd triangle: 48
4th triangle: 48
144 + 48 + 48 + 48 + 48 = <u>336 cm squared</u>
Answer = a) 2.57 because it is to the most number of decimal places so it is the most accurate
