A rectangle with width 1.6 centimeters is enlarged to a rectangle with length 25 centimeters and width 8 centimeters. What is the area of the original rectangle? 8 cm² 20 cm² 25 cm² 40 cm²

Hey there! I'm happy to help!

We see that the width goes from 1.6 to 8. How much bigger is 8 and than 1.6?

8/1.6=5

8 is 5 times bigger than 1.6, so this rectangle is 5 times larger than the original. Let's find the area of the big triangle.

25(8)=200

And then divide by 5. This will give us the smaller triangle.

200/5=40

Therefore, the answer is 40 cm².

Have a wonderful day! :D
