<u>Answer:</u>

The area of the triangle PQR is 90 cm^2.

<u>Step-by-step explanation:</u>

We are given two triangles, ABC and PQR, which are similar to each other.

If two triangles are similar, then the ratio of their areas is the square of the ratio of their sides.

Given that area of the triangle ABC is 40cm^2, we are to find the area of the triangle PQR.

Finding the scale factor k=\frac{6}{4} =1.5

So square of this scale factor will be k^2=(1.5)^2=2.25

Area of triangle PQR = 2.25 \times 40 = 90cm^2

Answer:

90cm^2

Step-by-step explanation:

The side length AB of triangle ABC corresponds to side length of PQ of triangle PQR.

The scale factor from ABC to PQR is k=\frac{6}{4}=1.5

The area of triangle PQR will change by k^2=1.5^2=2.25 centimeters square.

Since we know the area of triangle ABC to be 40cm^2, the area of triangle PQR =2.25\times 40=90cm^2

BaLLatris [955]

Answer: $96,220

Step-by-step explanation:

From the questionwe are we informed that Daniel is a very good television salesperson and that his annual sales average at $187,400 and his commission on sales is 30% while his annual base salary is $40,000.

His annual gross income will be his annual base salary plus commission annually. This will be:

= $40,000 + (30% × $187,400)

= $40,000 + (0.3 × $187,400)

= $40,000 + $56,220

= $96,220
