Find the area of an equilateral triangle that has a perimeter of 21 inches Round the answer to one decimal place?
Find the area of an equilateral triangle that has a perimeter of 21 inches. Round the answer to one decimal place.
An equilateral triangle has a perimeter of 27 inches What is the length of each side?
9 inches
Carey drew an equilateral triangle with a perimeter of 45 inches. He dilated the triangle by a scale factor of 0.6. What is the length of each side of the image of the dilated triangle?
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
What is the area of an equilateral triangle with sides of 10 inches and 7 inches?
By definition, an equilateral triangle has all three sides of equal length! So it is impossible for it to have sides of length 10 inches and 7 inches!
The perimeter of an equilateral triangle is 90 inches If a pentagon were constructed with each side being 2 inches longer than each side of the triangle how many inches would the total perimeter of?
Solve the problem in stages:Solve for the length of the triangle side.Perimeter = sum of all the sides. As equilateral, all sides equal so 3 x side_length = 90 inside_length = 90in / 3 = 30in.Pentagon side is triangle_side + 2in, thus Pentagon_side = 30in + 2in = 32inThere are 5 sides to a pentagon, each 32in long, so its perimeter is 5 x 32in = 160in.
