# Can you awnser this math question?

Angela wants to turn an ordinary tablecloth into a holiday tablecloth by edging it with a seasonal border. If the area of the square tablecloth is 25 square feet, how many feet of border does Angela need?

Draw a square. If the number of boxes made by equal lines in it each way (like tic-tac-toe lines) equals 25 boxes, how many squares are on each side? In other words, what number (on a side) times itself (it’s a square) equals 25? Put that number on each side of the square. That’s how many feet each side of the tablecloth is.

Think about a border like lace that she will add to the entire edge, all around. It will touch all four sides. That will be 4 (sides) times the length of a side (how many feet do you have written there?). That’s the answer.

In other words, the AREA of a square is the length of a side times itself.

The PERIMETER of a square is the legth of a side times 4.

You know that the tablecloth is square. That means once you know 2 sides you automatically know the other 2 sides. The area of a square is A=base x height. The area is 25 square feet which is 5 x 5. Now knowing that base is 5ft and height is 5 ft and other 2 sides are equal… all 4 sides are 5 ft. Add them up and the border will be 20 ft.

AREA OF THE SQUARE=25=5*5

SO EACH SIDE=5 FT

FOR THE LACE WE NEED PERIMETER=4X5=20 FT

20 feet.

25=5*5

So 5*4=20

Tell me: What grade are you in?
