An equilateral triangle with a side length of 6mm and a height of 5.2mm is divided vertically into halves. Find the area of one
Viefleur [7K]

There are two ways you could go about solving this.

You could divide the length of the base (6mm) by 2 and use that to find the area or you could find the area of the whole triangle using 6mm and divide that by 2.

I will use the first method I described:

base = 6/2

base = 3 mm

height = 5.2 mm

area = bh/2

area = (3 * 5.2)/2

area = 7.8 square mm

(don't forget your units)


Using the other method would look like this:

area = bh/2

b = 6

h = 5.2

area = (6 * 5.2)/2

area = 15.6 square mm

area/2 = 7.8 square mm


As you can see either method yields the same result.

Hope this helped.

Cheers and good luck,

Brian

What is the volume of a rectangle prism 11inches long, 6 inches wide and 3 inches high
borishaifa [10]

Answer:

198 inches^3

Step-by-step explanation:

Volume of a rectangular prism = Length × width × height

Length = 11 inches

Width = 6 inches

Height= 3 inches

Volume of a rectangular prism = Length × width × height

= 11 inches × 6 inches × 3 inches

= 198 inches^3

The volume of the rectangular prism with dimensions 11 inches long, 6 inches wide, 3 inches high is 198 cubic inches

Ishaan is 3 times as old as Christopher and is also 14 years older than Christopher.
aniked [119]
<span>The correct answer is: 21

Explanation:
Let's first assume few variables!

x = Ishann's age (in years)
y = Christopher's age (in years)

1. Ishann is 3 times as old as Christopher can be represented mathematically as:
x = 3y ---- (1)

2. Ishann is 14 years older than Christopher can be represented mathematically as:
x = y + 14 ---- (2)

Get the value of y from Equation (1) and plug it in Equation (2):

(2) => x = (x/3) + 14
3x = x + 42
2x = 42
x = 21

Hence Ishann is 21 years old!</span>
