Question

a diagonal of a quadrilateral is 30 M in length and the perpendicular to it from the opposite sides are 6.8 and 9.6 find the area of a quadrilateral

Answer 1

Answer:

246 sq M

Step-by-step explanation:

In ΔABC, PQ is height and AC is base.

similarly, in ΔADC, DP is height and AC is base.

Area of quadrilateral ABCD = ar(ABC) + ar(ABC)

                                              = 1/2×30×6.8 + 1/2×30×9.6

                                               =1/2×30(6.8+9.6)

                                               =15×16.4 = 246 sq M
