Question

Sides of three square rooms measure 13 feet each, and sides of two square rooms measure 15 feet each. Which expression shows the total area of these five rooms?

do i multiply 13 and 15 ?

Answer 1

Nope, you take the area of each square separately...


So for the first 3 squares with sides of 13 :

13*13=165

165*3 = 495

15*15=225
225*2 = 450

495+450=945
