I need help understanding how to do this.

Area of a trapezium = 1/2 * sum of parallel sides * distance between them

= 1/2 * (10 + 18) * 6

= 1/2 * 28 * 6

= 84 feet ^2

Area of a rectangle = length * breadth

= 18 * 12

= 216 feet ^2

Total Area = 84 + 216

Total area = 300 feet

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube

320ft

step-by-step explanation:

120 divided by 3 equals 40

40 times 4=160

160 times 2=320
