Identify the lateral area and surface area of a regular triangular pyramid with base edge length 6 cm and slant height 13 cm.
Law Incorporation [45]

The lateral area is 117 square centimeters and the surface area is 292.72 square centimeters

<h3>How to determine the lateral area?</h3>

The given parameters are:

  • Base length (b) = 6
  • Slant height (l) = 13

The lateral area is calculated using:

Lateral = 0.5 * (Perimeter of base) * Slant height

This gives

Lateral = 0.5 * (3 * 6) * 13

Evaluate

Lateral = 117

Hence, the lateral area is 117 square centimeters

<h3>How to determine the surface area?</h3>

The surface area is calculated using:

Surface = l²√3

This gives

Surface = 13² * √3

Evaluate

Surface = 292.72

Hence, the surface area is 292.72 square centimeters

A triangle has height of 15 in. and area of 120 in^2. what is the length of the base?
Klio2033 [76]
Area = 1/2 x base x height
120 = 1/2 x 15 x base = 15/2 x base
base = (2 x 120)/15 = 16 in.

The product of 3x and (3x+1) is a t least 35
Leokris [45]
Product means the sum of two things i.e. the product of 1 and 2 is 3 <span>(1 + 2 = 3)

So the product of 3x and (3x+1) can be written as:
35 < 3x + 3x + 1
^ Greater than 35 i.e. at least 35
35 < 6x + 1
34 < 6x
34/6 < x
17/3 < x
5.67 (2dp) < x
