Can someone me find areas of similar figures. ill give brainlest and points

Therefore the Area of ΔEDF is 9.6 in².

Step-by-step explanation:

Given:

ΔBAC ~ ΔEDF

EF = 4 in

BC = 5 in

Area of ΔBAC = 15 in²

To Find:

Area of ΔEDF = ?

Solution:

If two triangles are similar, then the ratio of the area of both triangles is proportional to the square of the ratio of their corresponding sides.

This proves that the ratio of areas of two similar triangles is proportional to the squares of the corresponding sides of both the triangles.

ΔBAC ~ ΔEDF  ........Given

Therefore we will have

Substituting the values we get

Therefore the Area of ΔEDF is 9.6 in².

step-by-step explanation:

1699/ 8548

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
