Parameter of rectangle equal parameter of triangle?

I hope you want to know the Perimeter. Perimeter is the total length of the boundary of the region bounded by a shape. For a rectangle it is the sum of the 4 bounding sides, or 2*(L+B), where L is Length of the rectangle and B is Breadth of the rectangle. For a Triangle it is the sum of the 3 sides. If you consider an equilateral triangle. By property the 3 sides of an equilateral triangle are equal. Hence the Perimeter of an equilateral triangle is denoted as; 3*a, where a is the length of one of the sides of the triangle. It is possible that the perimeter of a rectangle is same as that of many different types of triangles. We can formulate a relationship for a special case where the perimeter of a rectangle is equal to the perimeter of an equilateral triangle; P(R) = P(ET), P(R) is perimeter of rectangle and P(EQ) is perimeter of Equilateral triangle. P(R)=2(L*B) = P(EQ) = 3*a; hence, a = (2/3)*(L*B) = P(R)/3. i.e., the sides of the Equilateral triangle are one thirds of the perimeter of the rectangle.


Can different shapes have the same perimeter?

Yes. Ex: A 5"x4" rectangle has the same perimeter as an equilateral triangle with sides 6" long.


What is the perimeter and area of an equilateral triangle with a side of 8?

Perimeter of equilateral triangle: 24 units Area of equilateral triangle: 27.713 square units rounded to three decimal places


What are three shapes that have a perimeter of 12 cm?

Square side 3cm. Rectangle 2cm x 4cm. Equilateral triangle side 4cm.


What is the perimeter for a equilateral triangle with 7.8mm sides?

Perimeter is the sum of the sides. An equilateral triangle has three sides of equal length. So the perimeter in this case would be 7.8mm x 3 = 23.4mm.

What is the area of an equilateral triangle that has a perimeter of 71 feet?

Find the area of an equilateral triangle if its perimeter is 18 ft


What are three shapes that have a perimeter of 12 cm?

Square side 3cm. Rectangle 2cm x 4cm. Equilateral triangle side 4cm.


What is the perimeter of an equilateral triangle if each side is 40centimeters?

Each side of an equilateral triangle is 9.2 ft, what is the perimeter of the triangle? Solution: 27.6 ft. The perimeter of a triangle is total length of all three sides added up. An equilateral triangle has 3 equal sides. So the perimeter is 9.2×3=27.6 ft.


The perimeter of an equilateral triangle is 63m what is the measure of one side of the triangle?

An equilateral triangle has three sides of the same length. Therefore, the length of each side of an equilateral triangle with a perimeter of 63 metres is equal to 63/3 = 21 metres.


What is the perimeter of an equilateral triangle with one side 10.5?

An equilateral triangle has all three sides the same length. → perimeter = 3 × 10.5 = 31.5 units.


What is the ratio of the length of a side of an equilateral triangle to its perimeter?

Length of a side of an equilateral triangle : Perimeter = 1 : 3 For example, if the length of the sides of an equilateral triangle were 5cm each, then perimeter would be three times that much - 15cm. 5 : 15 is the same as 1 : 3 when simplified.
