We would divide the shape into a rectangle and a trapezium

The rectangle is of length, 24.5 ft and width 10.75 ft

Area = 24.5 * 10.75 = 263.375 square feet.

Trapezium : Parallel sides are 18.5 ft and 24.5 ft
Height: 12 - 10.75 = 1.25ft

Area of Trapezium = (1/2)*(Sum of Parallel sides)*height

= 1/2 * (18.5+24.5)* 1.25
= 1/2 * 43* 1.25 = 26.875

Total Area = Area of Rectangle + Area of Trapezium

= 263.375 + 26.875 = 290.25

Area = 290.25 ft² (D)

T he equation for a parabola with directrix y = –p and focus (0, p) is:

zhuklara [117]

The equation for a parabola with directrix y = –p and focus (0, p)

The distance between vertex and directrix is P

Also the distance between vertex and focus is also P

Focus (0,p) so focus lies on y axis

Directrix line is paralled to focus point

So Directex crosses the x axis .

Hence line of symmetry lies is the y-axis.
