Question

From a rectangular sheet of tin, of size 100 cm by 80 cm, are cut four squares of side 10 cm from each corner. Find the area of the remaining sheet.

Answer 1

Answer:

7600 cm^2

Step-by-step explanation:

area of rectangular sheet = l*b = 100 *80 = 8000 cm^2

now

side of square = 10 cm

area of square = side ^2 = 10^2 = 100 cm^2

as four squares are cut

so

4*100 = 400 cm^2

area of remaining sheet = (8000-400)cm^2 = 7600 cm^2

hope it helps
