Question

Which expression shows the total area of 5 rooms, if the sides of
3 rooms measure 17 feet each, and the sides of 2 rooms measure
15 feet each?

Answer 1

area= length times width
a= l x w

but since you are calculating for five rooms, multiply the area of one rom by 5
so total area will be \(\Large A=5 (l \times w)\)
