Not by adding, but doubling (multiplying by 2) will work.
Doubling the base of a triangle while keeping the height constant will double the area of the triangle. The area of a triangle is directly proportional to its base length, so increasing the base length by a factor of 2 will result in the area being multiplied by 2 as well.
If the length of each side is doubled, then the perimeter is also doubled.
Find the perimeter by adding the lengths of the sides
Doubling those two dimensions would quadruple the area. So new area = 4*34 cm2 = 136 cm2
If you have the length of each of the three sides of a triangle, you can find the perimeter of (the distance around) the triangle by adding the length of the sides. Their sum will be the perimeter of this geometric shape.
If a triangle does not have the same length side as another triangle the sides are not congruent.
-- Area of a triangle = 1/2 of (length of the base times height) -- Perimeter of a triangle = (length of one side) + (length of another side) + (length of last side)
Use Pythagoras' theorem: 82+92 = 145 and the square root of this is the answer.
No way to tell as we don't know an angle or another side.
-- Find the length of one side. -- Find the length of another side. -- Find the length of the remaining side. -- Add the three numbers. -- Their sum is the perimeter of the scalene triangle.
-- Measure or calculate the length of one side. -- Measure or calculate the length of another side. -- Measure or calculate the length of the only remaining side. -- Add the three numbers. The sum is the perimeter of the triangle.
An isoceles triangle has two angles that are the same length with the third being different. It can be a right angle or another angle. or it's also called a Right Isosceles triangle.
