I quite don’t get this question and I have 4 minutes remaining

The length of one of the sides of the larger pentagon is 24 cm. The length of one of the sides of the smaller pentagon is 8 cm.

24÷8=3

So, if the larger pentagon is 3x the size of the smaller pentagon, we can find the area of the smaller pentagon by dividing the area of the larger pentagon by 3.

135÷3=45

The area of the smaller pentagon is 45in²
