An equilateral triangle has sides 8 units long. An equilateral triangle with sides 4 units long is cut off at the top, leaving a

Darina [25.2K]

Answer:

1:3

Step-by-step explanation:

Please study the diagram briefly to understand the concept.

First, we determine the height of the isosceles trapezoid using Pythagoras theorem.

$4^2=2^2+h^2\\h^2=16-4\\h^2=12\\h=\sqrt{12}\\ h=2\sqrt{3}$ units$

The two parallel sides of the trapezoid are 8 Inits and 4 units respectively.

Area of a trapezoid $=\dfrac12 (a+b)h$

Area of the trapezoid

$=\dfrac12 (8+4)*2\sqrt{3}\\=12\sqrt{3}$ Square Units$

For an equilateral triangle of side length s.

Area $=\dfrac{\sqrt{3}}{4}s^2$

Side Length of the smaller triangle, s= 4 Units

Therefore:

Area of the smaller triangle

$=\dfrac{\sqrt{3}}{4}*4^2\\=4\sqrt{3}$ Square units$

Therefore, the ratio of the area of the smaller triangle to the area of the trapezoid

$=4\sqrt{3}:12\sqrt{3}\\$Divide both sides by 4\sqrt{3}\\=1:3$
