Hey there!
Each step is three feet. This can be represented by 3s= feet. We can plug that in to figure out our side lengths.
20(3)=60
40(3)=120
Now we can multiply these two together to get the area.
120(60)= 7,200
Therefore, his backyard is about 7,200 square feet.
I hope this helps!

Answer:
<u>The area of the larger triangle is 315 inches²</u>
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)
<u>Area of the larger triangle = 630/2 = 315 inches²</u>
