Area

21,615 square feet is about 1/2 acre (0.496212121)acres.

1 metre = 3.281 feet so 3 metres = 9.843 feet.

21 ft * 17 ft = 357 sq feet.

95 inches = 2,413 millimeters.

2940 sq. inches

Four million.

36 square feet = 4 square yards.

67 x 144 (inches per square foot) = 9648 / 324 (18 x 18) = 29.77 tiles

41'X41'= 1681sf = 0.038590 acres

Answer: 6253 ft² = 580.922 m²

36 square miles = 23,040 acres.

None. Unless it's SQUARE LEAGUE.

Without knowing the height of the room then only the floor (or ceiling) area (A) can be calculated.

A = Length x Width

A = 14 x 10 = 140 square feet.

A square yard is 9 times greater than a square foot.

An acre is a unit of area, equal to 43560 square feet (1/640th of a square mile)

598*610 = 364,780 square metres

Six sheets will exactly cover it, without cutting anything.

One square kilometre measures 1000 m in each direction. i.e. 1 000 000 square metres. The shape may be arbitrary, as it often is in parcels of land.

So your 4046.82 square metres is 4046.82/1 000 000 - about 0.0404, but check the math.

A fool's thinking goes as follows:

Each cart is 4*2.5 = 10 sq feet.

There are 216 sq feet so there is enough space for 216/10 = 21.6 or 21 carts.

This answer completely overlooks the possibility that the 216 square feet may be in the form of a long narrow corridor that is 2 ft wide (and 108 ft long). In that case you will not get even one cart in!

Two rods is 33 feet.

This question cannot be answered sensibly. A square foot is a measure of area, with dimensions [L2]. A metre is a measure of distance, with dimensions [L]. The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.

The top and bottom are 30 square feet each.

The left and right sides are 45 square feet each.

The front and back are 1.5 square feet each.

40 inches by 13 feet equates to 43.33 square feet.
