area of triangle = 0.5 x base x height area = 0.5 x 20 x 40 area = 400 ft2
40 x 20 = 800 square feet
20-ft x 40-ft x 3-in = 20-ft x 40-ft x 1/4 foot = 200 cubic feet = 7.41 cubic yards

area of triangle = 0.5 x base x height area = 0.5 x 20 x 40 area = 400 ft2
40 of 20 = 40 x 20 = 800 40% of 20 = 0.4 x 20 = 8
Area = Length X Width.A = 20' X 40'A = 800'^2 ( Or 800 Feet Squared.)
40 x 20 = 800 square feet
20-ft x 40-ft x 3-in = 20-ft x 40-ft x 1/4 foot = 200 cubic feet = 7.41 cubic yards

Area= 1/2 x base x height So, 40 squared= 1/2 x 20x h 40 squared= 10h 40/10=10h/10 4 = height
133.3 cubic feet
40 NO. 20 x 2 = 40; 20 x 20 = 400
20 x 40 = 800 800 x 52 = 41 600
40% of 600: = 40% x 600 = 0.40 x 600 = 240 20% of 40% of 600: = 20% x 240 = 0.20 x 240 = 48
20 x 40 = 800
