Matt is framing his favorite poster.The poster is 30 inches wide and 50 inches long. How many square inches of glass will he need to frame the poster ?

Respuesta :

I believe that you just have to multiply 30 and 50 which will equal to 1,500 square inches of glass.
You need to find the area, so we know that the formula for the area of a rectangle is A=lw, so we need to set up the equation.
A=lw
A=50*30
A=1500 square inches of glass
