Subtract the two side lengths from the perimeter. The perimeter of a triangle is just the length of the 3 sides added together. Eg. Q: A triangle has a perimeter of 20 m. One side is 5m and another is 10m. How long is the 3rd side? A: Perimeter - side 1 - side 2 = side 3 Side 3 = 20 - 5 - 10 = 5 m
Perimeter -2 known sides = 3rd side 180 -2 known angles = 3rd angle
The perimeter of a square is the sum of the lengths of its sides, while the area is the square of one of its sides. That is, if each side is S units long, then Perimeter = 4*S units and Area = S*S square units.
Hint: the perimeter of a square is the sum of its four sides, so each side is one-quarter of the perimeter...
You would need a measure of each side, and the total perimeter (all sides). Dividing the perimeter by the length of one side gives the number of sides.
Perimeter = sum of three sides = 96 cm One side of 34cm, another of 25 cm so the third is 96 - 34 -25 = 37 cm
The perimeter is the sum of the three sides.
Subtract the two side lengths from the perimeter. The perimeter of a triangle is just the length of the 3 sides added together. Eg. Q: A triangle has a perimeter of 20 m. One side is 5m and another is 10m. How long is the 3rd side? A: Perimeter - side 1 - side 2 = side 3 Side 3 = 20 - 5 - 10 = 5 m
The lengths of two sides are not enough to determine the perimeter of a triangle: Either the third side or else the angle between the two given sides is also needed. If two of the sides are 10m and 25m, then the third side can be anything between 15m and 35m, and the perimeter can be anything between 45m and 70m.
Perimeter of rhombus = 4*side = 9.6 cm
Side # 1 - 40Side # 2 - 20Side # 3 - 16
If it is an equilateral triangle with 3 equal sides of 4m then its perimeter is 12cm
25cm x 4 sides = 100 cm perimeter
lol how many sides? perimeter divided by sides equals length per side. 44/4 =11 then again 44/11=4.. how many sides?
Since a pentagon has 5 sides, you divide the perimeter by 5.
No because are is the in side and perimeter is the out side of all the sides..............
Use two sides and Pythagoras's theorem to work out the third side. Then simply add the three sides.
