Mamont248 [21]

Answer:

A=6\sqrt{5}\ units^2

Step-by-step explanation:

we know that

Heron's Formula is a method for calculating the area of a triangle when you know the lengths of all three sides.  

so

A=\sqrt{s(s-a)(s-b)(s-c)}

where

a, b and c are the length sides of triangle

s is the semi-perimeter of triangle

we have

a=9\ units,b=4\ units,c=7\ units

Find the semi-perimeter s  

s=\frac{9+4+7}{2}=10\ units

Find the area of triangle

A=\sqrt{10(10-9)(10-4)(10-7)}

A=\sqrt{10(1)(6)(3)}

A=\sqrt{180}\ units^2

Simplify

A=6\sqrt{5}\ units^2

The area of a sail is 40 1/2 square feet. The base and the height of the sail are equal. What is the height of the sail (in feet
grin007 [14]
Both base and height of the sail is 40 1/2 feet.

A sail is triangular in shape. Finding the area of a triangle is multiplying its base and height and dividing the product by 2.

A = 1/2 bh

Area = 40 1/2 or 40.50 sq. ft
Since base and height are equal.
40.50 x 2 = 81
bh = 81
bh = 81 ÷ 2
b = 40 1/2 ft
h = 40 1/2 ft

Which statement is false?
tankabanditka [31]

Answer:Choice A)  All points with an x-value of 3 are located in Quadrant I.

We can show it is false through the use of a counter example. For instance, the point (3, -5) is not in quadrant 1, but rather in quadrant 4.

We would need to say "all points with x value 3 and positive y value" to ensure the point is in quadrant 1.
