Answer:
The area of the strip cut out is 816 sq.cm
Step-by-step explanation:
Length of the sheet L=50 cm
Breadth of the sheet B=30 cm
Area of Sheet = L × B
= 50 × 30
= 1500 sq.cm
A Strip 6 cm wide is cut from all around so
Length of remaining sheet = 50 -6-6 = 38 cm
Breadth of remaining sheet = 30-6-6 = 18 cm
Area of remaining sheet = 38 × 18 = 684 sq.cm
Area of Strip cut out = 1500 - 684= 816 sq.cm
Therefore, The area of the strip cut out is 816 sq.cm.
