WebA perfect triangle is one having integers for sides for which the area is numerically equal to the perimeter. Show that the triangles with the given side lengths are perfect. (a) 6, 25, 29 (b) 9, 10, 17 (a) To show that the triangles are perfect, show that the area is numerically equal to the perimeter for each triangle. Begin by finding the ... WebArea of an equilateral triangle $= \frac{\sqrt{3}a^2}{4}$ square units. Properties of Equilateral Triangle. All sides are equal in length. All angles are congruent. Each angle measures $60^\circ$. Thus, it is equiangular. It is a regular polygon. The area of an equilateral triangle is $\frac{\sqrt{3}a^2}{4}$. The perimeter of an equilateral ...

Let s equal the "semi-perimeter" of AABC a+b+c 2 8 = The area of AABC is A = √√s (s – a) (s – b) (s — c) Your friend just bought a triangular plot of land to open a dog daycare center. The lengths of each side of the triangle plot of land is 225 ft, 900 ft, and 850 ft. WebKnowing two sides of a right triangle and needing the third is a classic case for using the Pythagorean theorem. In simple (sort of), the Pythagorean theorem says that sum of the squares of the lengths of the legs of a right triangle is equal to the square of the length of its hypotenuse. Every right triangle has three sides and a right angle. top athens outdoor activities

What can be the perimeter of the triangle? Solution: Given, the triangle is the isosceles triangle. Thus, any two sides of the triangle are equal. So, the third side can be either 5cm or 6cm. WebA formula for perimeter for * squares* is 4 s_ (with _s being the side length). The problem states that one side is equal to 7 m. So in the equation, replace s with 7. So the equation is now 4 (7) = P (P is perimeter) 4 times 7 = 28 m, and that's how they got 28 m. 1 comment ( 6 votes) Show more... 240480 2 years ago why is it called a perimeter? • top atheist quotes
