Sam will get a piece of the triangular tin plate whose base is 12 inches and whose height is 15 inches from a piece of tin plate that measures 36 inches by 25 inches. How many square inches will be left of the rectangular piece often Sam gets what he needs?
+37084 Recall the area of a triangle = 1/2 base x height
the area of the sheet from which the triangle area is subtracted is l x w
so l x w - 1/2 base x height = remaining sheet area
36 x25 - 1/2 x12 x 15 = 810 sq inches
