The following exercise uses heron's formula one triangular plot has sides 5 yards, 6 yards, and 7 yards. another has sides 3 yards, 6 yards, and 7 yards. find the area of each plot. (round your answers to one decimal place.) first plot second plat which plot endloses the larger area? first plot second plat

1st plot encloses the larger area.

Step-by-step explanation:

We have been given the sides of two triangles. We are asked to find the area of given triangles using Heron's formula.

The area of a triangle with sides a, b and c would be:

, where S is the semi-perimeter of triangle.

Substitute given side lengths:

Therefore, the area of 1st plot would be 14.7 square yards.

Substitute given side lengths:

Therefore, the area of 2nd plot would be 8.9 square yards.

Since area of first plot is greater than 2nd plot, therefore, 1st plot encloses the larger area.

answer:   rlly

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
