Question

Из листа стекла шириной 65см и длиной 76см нужно вырезать прямоугольный кусок размером 52 см на 37 см . Найдите площадь оставшейся части стекла.

Answer 1

65*76=4940(см2)
52*37=1924(см2)
4940-1924=3016(см2)

Answer 2

Calculating the Remaining Glass Area

To find the area of the remaining piece of glass after cutting out a rectangular piece, we can use the formula for the area of a rectangle: Area = Length x Width.

Given: - Original width of the glass (W): 65 cm - Original length of the glass (L): 76 cm - Size of the cut piece: 52 cm x 37 cm

We can calculate the area of the remaining piece of glass using the following steps:

1. Calculate the area of the original piece of glass. 2. Calculate the area of the cut piece. 3. Subtract the area of the cut piece from the area of the original piece to find the area of the remaining glass.

Calculation Steps

1. Calculate the area of the original piece of glass: - Area of original piece = Length x Width - Area of original piece = 76 cm x 65 cm - Area of original piece = 4940 square cm

2. Calculate the area of the cut piece: - Area of cut piece = Length x Width - Area of cut piece = 52 cm x 37 cm - Area of cut piece = 1924 square cm

3. Calculate the area of the remaining piece of glass: - Area of remaining piece = Area of original piece - Area of cut piece - Area of remaining piece = 4940 square cm - 1924 square cm - Area of remaining piece = 3016 square cm

So, the area of the remaining piece of glass is 3016 square cm.

This calculation assumes that the cut is made without any loss of material and that the edges of the cut are perfectly straight and perpendicular.
