Question

Find d1 when area is 114ft and d2 is 12ft

Answer 1

Answer:

  19 ft

Step-by-step explanation:

Apparently, we are to assume the figure is a kite and that the diagonals cross at right angles. The area of such a figure is ...

  A = (1/2)(d1)(d2)

Filling in the numbers, we get ...

  114 ft^2 = (1/2)(d1)(12 ft)

  d1 = (114 ft^2)/(6 ft) . . . . divide by the coefficient of d1

  d1 = 19 ft
