The area of a rectangle yard with a width of 6a^2b feet is 72a^3b^4 square feet. What is the length?

12ab^3

Step-by-step explanation:

Given that:

Area of rectangle = 72a^3b^4

Width of rectangle = 6a^2b

Area = Length * Width

Length = Area / Width

Length = 72a^3b^4 / 6a^2b

Length = 72 / 6 * a^3 / a^2 * b^4 / b

Length = 12 * a * b^3

Length = 12ab^3

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.

answer: .64
