It is: 8*5 = 40 square inches
8 square feet is the area.
40 square units
40 square feet. Multiply length by width - the result is the area in square feet.
Surface area = 2*(8*5 + 5*2.5 + 2.5*8) = 2*(40 + 12.5 + 20) = 2*72.5 = 145 square units.
If the area of the square is 64 square cm then its sides are 8 cm. Its perimeter: 8+8+8+8 = 32 cm
It is: 0.5*(5+8)*8 = 52 square units
It is: 8*5 = 40 square inches
Total square feet: 40.0
5' x 8' is 40 square feet. Multiply length by width - the result is the area in square feet: 5 x 8 = 40
1/2*base*height = area 1/2*8*5 = 20 square units
If the square has sides of 8 meters then its area is 8*8 = 64 square meters
8 square feet is the area.
