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

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
