Answer from: Thahani

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 $=2.25\times 40=90cm^2$

Answer from: zahradawkins2007

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

Step-by-step explanation:

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
