155 square meters equates to about 1,668.4 square feet.

From the Pythagorean theorem, leg1squared plus leg2 squared = hypothenuse squared. If leg 1 = 124 and hypothenuse is 155 then 155 squared - 124 squared is 8649 and the leg2 is square root of 8649 = 93 cm

There are 12 inches in a foot, and there are 12 x 12 square inches in a square foot. Lock that idea in. One square foot equals 12 x 12 square inches. That's 144 square inches in one square foot. An area of 155 square feet contains 144 x 155 square inches, or 22,320 square inches.
