Trapezoid - diagonal

A trapezoid has a length of diagonal AC crossed with diagonal BD in the ratio 2:1. The triangle created by points A, cross point of diagonals S and point D has area 164 cm2. What is the area of the trapezoid?

Correct answer:

S =  382.7 cm2

Step-by-step explanation:

SΔASD=164 SΔSDC=164/3 SΔSCB=164 SΔABS=??  S=SΔASD+SΔSDC+SΔSCB+SΔABS S=382.7 cm2
