Answer:
20.4131
Step-by-step explanation:
You need to have only 4 decimal places after , last decimal being approximated
I believe the correct answer is he paid the right amount
First let’s call the square shape A and the rectangle shape B.
To find the area of shape A you do 24 x 24 = 576cm squared
To find the area of shape B you do 40 x 24 = 960cm squared
To find the total area you just add the two areas together
576 + 960 = 1536cm squared
4(a-2)=3(a+4)
4a-8=3a+12
a=20
