Two triangles are similar with a scale factor of 3. the preimage triangle has a base of 7 inches and a height of 10 inches. what is the area of the larger triangle? formula: area = 1/2 (base)(height)

The area of the larger triangle is 315 inches²

Step-by-step explanation:

1. Let's review all the information provided for answering the questions properly:

Pre-image triangle has a base of 7 inches and a height of 10 inches

Scale used : Factor of 3

2. What is the area of the larger triangle??

For calculating the area of the larger triangle, we use the scale this way:

Base = 7 inches * 3

21 inches

Height = 10 inches * 3

30 inches

Area of the larger triangle = 1/2 (Base * Height)

Area of the larger triangle = 1/2 (21 * 30)

Area of the larger triangle = 630/2 = 315 inches²

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7
