Answer:

261.98 is the value of the given expression.

Step-by-step explanation:

We have to find the value of the following expression:

$4.659\times 104 - 2.14\times 104$

Using the associative property, we can write and solve the given expression as:

$(4.659 - 2.14)\times 104\\=2.519\times 104\\=261.976$

Rounding off the answer, we get,

$261.976\approx 261.98$

Thus, 261.98 is the value of the given expression.

Since the triangles are similar, the ratio of the sides of larger triangle to the smaller triangle is a constant.

That constant = $\frac{15}{9} = \frac{5}{3}$

Since the sides are in that constant proportion, the area of the triangles will also be in proportion.

(Area of larger triangle) over (Area of smaller triangle) = $\frac{5}{3}$

$\frac{206}{x} = \frac{5}{3}$

$x = 206 * \frac{3}{5} = \frac{618}{5}$ = 123.6 ≈ 124

Hence, to the nearest whole number the area of smaller triangle is 124 ft².
