Step-by-step explanation:
To find perimeter, you need to add all the sides of the shape.
The area of a traingle is 1/2 bh.
You must find the "b" in order to find the perimeter.
Example:
A triangle has an area of 18 cm^2.
Therefore, the triangle has a 6 cm base and 6 cm height.
Then multiply the base by three to get 18 cm. That is your perimeter.
Bc length should be equal to each other
Answer:
In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1/x or x⁻¹, is a number which when multiplied by x yields the multiplicative identity, 1. The multiplicative inverse of a fraction a/b is b/a. For the multiplicative inverse of a real number, divide 1 by the number.
Step-by-step explanation:
To find the reciprocal, divide
