What is the perimeter of the triangle with an area of 30 mu? Add: is any triangle, can you calculate it?
This triangle is what kind of triangle, right triangle, or equilateral triangle. Otherwise, it cannot be calculated
Given that the three sides of the triangle are 5.13.12, what is the area of the triangle A.B.C
5^2=25
12^2=144
13^2=169
5^2+12^2=13^2
A triangle is a right triangle with 5,12 as the right side and 13 as the hypotenuse
S=1/2*5*12=30
Given the length of three sides of triangle a, B, C. how to calculate the area s?
1. Let's first look at Helen's formula: triangle area s = √ [P (P-A) (P-B) (P-C)], where p = (a + B + C) / 2a, B and C denote the side length of the triangle, and √ denotes the root sign, that is, the root sign of all the numbers in the brackets immediately following. 2. Let's look at the deformation of Helen's formula (where ^ denotes the square) s = √ [P (P-A) (P-B
