Philip is making a poster that is 36 inches long and 24 inches wide. He cuts out a rectangle that is 5 inches long and 12 inches wide from the poster. How much of the poster remains?

Respuesta :

Remaining area of poster = Area of Big rectangle - Area of small rectangle 
= (36*24) - (5*12) = 
= 864 - 60 = 804 in^2

Philip will have 804 inches remaining of his poster.
