True.
From the above number line we can say that, 6 and –6 are at the same distance of 6 units from 0 on the number line.
"hello students my name is megha and i am a tutor at leader learning in this q a video we will explore the concept of hedon's formula find the area of triangle whose sides are respectively 9 centimeter 12 centimeter and 15 centimeter so we have to find the area of triangle in which all the three sides of a triangle are equal so to whenever we have three different sides of a triangle we use heron's formula to find the value of area of triangle we use heron's formula to find the area of triangle area of triangle so what is the formula for area of triangle by heron's formula is under root of semi-parameter semi-parameter minus side a semi-parameter minus side b semi-parameter minus side c so here how do we find the semi-parameter semi-parameter means parameter divided by 2 and parameter is equals to sum of all the sides sum of all the sides means 9 plus 12 plus 15 centimeters divided by 2 so it will be equals to 5 15 and 10 25 and 35 and 36 divided by 2 so semi-parameter will be equals to 18 centimeters now put the value of semi-parameter in the area of triangle to find the area of triangle now it will be equals to 18 centimeter into 18 minus 9 centimeter into 18 minus 12 centimeter into 18 minus 15 centimeters so it will be equals to 18 18 minus 9 is 9 18 minus 12 is 6 and 18 minus 15 is 3 so after calculating it you will find the value as 2 9 1 6 which is the under root under root of 2 1 2 9 1 6 is 54 units so our answer will be 54 square centimeters if you have any query in this question please drop a comment below and subscribe to our channel for more updates thank you "
