Answer:
D. greater than 8 cm and less than 70 cm
Step-by-step explanation:
Given:
Length of one side = 39 cm
Length of other side = 31 cm
We need to find the length of third side.
Solution:
to find the length of third side we will use triangle Inequality property which states that;
"The length of the third side should be less than sum of the other two side."
Also;
"The length of the third side should be greater than difference of the other two sides."
Now Sum of 2 sides of triangle = 39 + 31 =70 cm
Also Difference of 2 side of triangle = 39 -31 = 8 cm
Hence The length of the third side should be greater than 8 cm and less than 70 cm.

Answer:
- perimeter: 22 1/30 m
- area: 29 m²
Step-by-step explanation:
The perimeter is given by the formula ...
P = 2(L+W)
P = 2(4 7/20 +6 2/3) = 2(10 +61/60) = 2(11 1/60)
P = 22 1/30 . . . . meters
__
The area is given by the formula ...
A = LW
A = (4 7/20)(6 2/3) = (87/20)(20/3) = 87/3 = 29 . . . . square meters
The perimeter is 22 1/30 meters; the area is 29 square meters.
