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

false

explanation

these practices describe the manner the land use outcome is attained. land management methods implemented by corporations are a mandatory because they are a driver for better land use results economically, socially and environmentally. corporations are required to understand the connection between land use , and land management practices to support sustainable land use policies

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
