Use the vertex formula for finding the x-value of the vertex. The vertex is also the equation's axis of symmetry. The formula for finding the x-value of the vertex of a quadratic equation is x = -b/2a. Plug in the relevant values to find x.
Area of rectangle: 7 x 10 = 70 in2
Area of semicircle: (r^2*π)/2 = 3.5^2 * π /2 = 6.125*<span>π
</span>
=> Total area = 70 + 6.125*<span>π = 70 + approx 19.24 = approx. 89.24 in2</span>
------------------------------------------------------------------------------------------------------
The closest number here is 89 in2, so the answer is 89 in2.
