To work out the area of a rectangle, you need to multiply the length by the width. First, however, you need to make sure all units in the equation are the same, which they currently aren't. There are 100cm in a m, so we can convert from m to cm by multiplying by 100. Thus the dimensions here are 29 by 290cm. Multiply these together, and we get an area of 8,410cm2

2 m 29 cm or 2.29 m or 229 cm
First find the area in cm²Area = L x W160 cm x 170 cm =27 200 cm²10,000 cm² = 1 m² so divide you answer by 10,000 to get2.72 m²
1 m = 100 cm 1 sq m = 1 m x 1 m = 100 cm x 100 cm = 10000 sq cm ⇒ 0.01 sq m = 0.01 x 10000 sq cm = 100 sq cm A C7 envelope (big enough to hold a piece of A7 paper, or A6 paper folded in half, or A5 folded in quarters) is 8.3 cm by 11.2 cm which has an area of 8.3 cm x 11.2 cm = 92.2 sq cm. It should be quite possible to write your name and address on a piece of paper with an area of 0.01 sq m = 100 sq cm, for example a piece of paper 10 cm by 10 cm. Now that I've written my name and address on a piece of paper 10 cm by 10 cm, what should I do with it?
1 m = 100 cm 1 m² = 1 m × 1 m = 100 cm × 100 cm = 10,000 cm²
1 m = 100 cm 2 m = 200 cm 3 m = 300 cm 4 m = 400 cm . . . 8 m = 800 cm
