A carpenter had a rectangular board which measured 4m by 3m. He cut out a square piece side 125 cm.What is the ratio of the area of the cut out piece and the remaining piece?
Answers
Step-by-step explanation:
Length of the rectangular board = 4 m = 400 cm
Breadth of the rectangular board = 3 m = 300 cm
AREA of the rectangular board = LENGTH * BREADTH
= 400* 300 cm ^ 2
= 120000 cm^ 2
Side of a square piece = 125 cm
Area of a square piece = (125)^2 cm ^2
= 15625 cm^2
Remaining piece 's area = (120000 - 15625 )cm^2
= 104375 cm^2
Ratio of the area of the cut out piece to the remaining piece = 15625 / 104375
= 25 / 167
= 25 : 167

Step-by-step explanation:
length of rectangular board = 4m =400 cm
breadth of rectangular board=3m=300 cm
Area of rectangular board= length x breadth
= 400x 300 cm ^2
= 120000 cm ^2
Side of square piece = 125 cm
area of square piece = (125)^2 cm^2
=15625 cm
Remaining piece area =(120000 - 15625) cm^2
=104375 cm^2
Ratio of the area of cut out remaining piece= 15625/104375
=25/167
= 25: 167
