A rectangular window is 5 ft by 8 ft. Becky wants to replace the glass in the window. How many square feet of glass should she buy?
Um... 5ft*8ft=40ft^2?
is that 40 square feet?
Yes. It's 40 square feet.
To find the area of the rectangular window, we need to multiply its length and width. In this case, the length is 5 ft and the width is 8 ft.
To calculate the area, multiply the length by the width:
Area = Length × Width
Area = 5 ft × 8 ft
Area = 40 square feet
So, Becky should buy 40 square feet of glass.
