Web27 mei 2024 · The area is 44 We know that the area of any trapezoid is (AD+BC)/2*h To find the area we, therefore, only need to calculate h. We can see from the figure that FD=3 (this follows from AG=FD). Therefore FC=h=4 (The triplet 3,4,5 is a well known triplet for right triangles, but you also see it from 3^2+4^2=5^2) Therefore the area is (14+8)/2*4=44 WebHINT: ab +cd −(ad+ bc) = b(a−c)−d(a− c) = (a− c)(b −d) Alternatively, ab +cd = b(a −c)+ bc −(a −c)d +ad = (a− c)(b −d)+ad+bc we are reaching at the same point.

Then triangles ABE and ACF are similar, triangles DBE and DCF are similar. Using this facts, one can write A F A E = C F B E = C D B D = 3 4 D F D E = C D B D = 3 4 Then E F A E = 1 − A F A E = 1 4 E F D E = 1 + D F D E = 7 4 cosme healthcare
