If the size is 30 inches x 8 inches then the area = 30 x 8 = 240 square inches.
If the size was in feet, multiply 240 by 144.
Using Pythagoras it will be 30 times the square root of 2 which is about 42.426 inches to 3 dp
what i do is square it 30x30 = 900 devide it by 100 and x it by 78.5398 =706.858278.5398% is correct for doing it this way.(78.5398163397425)Improved answer:Area of a circle = pi*radius2Area = pi*152 = 706.8583471 square inches
4.75 square feet
Oh, dude, math time! So, 30 multiplied by 38 equals 1,140 square feet. It's like the area of a nice, cozy room where you can chill and watch Netflix all day. So, yeah, that's the size of your space if you ever need to know.
The square root of 900 is ±30 because 30 * 30 = 900 and -30 x -30 = 900
30 square inches converts to about 193.55 square centimeters.
30" x 30" = 900 square inches.
It is: 24 times 30 = 720 square inches
900 square inches in total.
30 in × 42 in = 1260 sq in
30 inches by 10 feet = 25 square feet.
2.5 Square feet is 30" x 30" or 360 Square Inches
30 inches by 5 feet = 12.5 square feet.
Area calculation: 30 inches by 30 inches = (30 x 30) square inches =900 square inches or, if you want square feet instead: 12 inches x 12 inches (1 square foot) = 144 square inches Take your 900 square inches and divide by 144 to get square feet. 900 / 144 = 6.25 square feet
5 square feet
30 x 18 = 540 square inches. 540 square inches converts to 3.75 square feet.
30 * 36 = 1080 square inches = 1080/144 = 7.5 sq. feet.
