2 1/2 * 7 = 17.5. she ran 7 days
The area of a rectangle is length times width or base times height
so 5 times 2x-3
if you multiply them together 5(2x-3) you would get 10x-15
there is no value of x
so the area would be 10x-15ft^2
The squares area can be calculated by multiplying width and length. Since these values are the same for the square, we can use exponents.
(6)^2 - (3)^2 - (2)^2 = area
The area is 23 square inches.
