Area is proportional to the square of the linear dimensions. If the linear dimensions are doubled, the area is increased by a factor of 22 = 4. The new area is 9 x 4 = 36 square inches.
the measure of the base in the similar triangle would be 24 inches because you are increasing by a scale factor of (3/1)
A triangle cannot have four lengths!
The area of triangle is : 35.0
12 inches
The dimensions are: altitude 12 inches and base 7 inches Check: 0.5*12*7 = 42 square inches
Ok if the triangle is equilateral then all the sides have to have the same length. Since the perimeter is 45 inches that means each side is 15 inches. 45 / 3 = 15 Now if he dilates the triangle by a scale factor of 0.6 we have to multiply the length of each side by 0.6. 15 * 0.6 = 9 So the answer is 9 inches
The scale factor is 3:1
the measure of the base in the similar triangle would be 24 inches because you are increasing by a scale factor of (3/1)
A golden triangle is an isosceles triangle such that bisecting one of the equal angles produces a new triangle that is similar to the original. It can be shown that the original triangle must be 72-72-36 degrees. Using trigonometry, or the similarity, it can be shown that the long sides were (1+Φ) times the shorter, where Φ is the golden ratio. So with the shorter side being 7 inches, the longer were 18.3 inches, approx.
A triangle with side lengths of 3, 4, and 5 inches is a scalene triangle.
It is a right angle triangle.
12 inches
Yes
The area of triangle is : 42.0
A triangle cannot have four sides.
A triangle cannot have four lengths!
Yes, it does. Your triangle has an area of 12.285 square inches and a perimeter of 23 inches.
