Answer:

Step-by-step explanation:

In the base we have the right triangle. Use the Pythagorean theorem for to calculate the hypotenuse:

$h^2=4^2+3^2\\\\h^2=16+9\\\\h^=25\to h=\sqrt{25}\\\\h=5\ ft$

The Lateral Area is the sum of the areas of three rectangles:

$4\ ft\ \times\ 2\ ft\to A_1=(4)(2)=8\ ft^2\\\\3\ ft\ \times\ 2\ ft\to A_2=(3)(2)=6\ ft^2\\\\5\ ft\ \times\ 2\ \ft\to A_3=(5)(2)=10\ ft^2$

The Lateral Area:

$LA=A_1+A_2+A_3\to LA=8+6+10=24\ ft^2$

A man owns 3/4 of the share of a business and sells 1/3 of his

quester [9]

Given:

A man owns 3/4 of the share of a business and sells 1/3 of his shares for Bir 10,000.

To find:

The value of the business in Bir.

Solution:

Let x be the value of the business.

It is given that a man owns 3/4 of the share of a business and sells 1/3 of his shares for Bir 10,000.

$x\times \dfrac{3}{4}\times \dfrac{1}{3}=10000$

$x\times \dfrac{1}{4}=10000$

Multiply both sides by 4.

$x=4\times 10000$

$x=40000$

Therefore, the value of the business is 40,000 Bir.
