How many square feet is a 35 foot by 102?

Answer 1

If you were to draw lines from the 35 foot side, parallel to the base, across to the other 35 foot side, there would be 35 lines if you put them 1 foot apart.

If you did the same from the base, up to the top - parallel to the 30 foot side, there would be 102 lines of they were 1 foot apart.

These lines would make lots of little 1 foot x 1 foot squares. There would be 35 in each column, and there would be 102 columns.... 102 x 35 = 3,570 squares - each 1 sq. ft.

So, 35 feet by 102 feet = 3,570 square feet.
