Question

in
a trapezoum
parallel
sides are 18 m and 60m
while non - parallel Sifles
are 20 and 34 m. find
area?​

Answer 1

Step-by-step explanation:

Parallel sides are = 18m 60m

non parallel sides = 20m 34m

altitude = ???? (x)

I can't draw the figure

18m AB

60m CD

20mAD

34mBC

altitude AE and BF

Now;

AB=EF =18m

so;

CD - EF = DE + CF

60 - 18 = DE + CF

42 = 2DE (common)

42/2 = DE

21 = DE

therefore DE = 21m

Now;

H² = P² + B²

(AD)²= (AE)² + (DE)²

20² = (AE)² + 21²

400 = (AE)² + 441

400 - 441 = (AE)²

41 = (AE)²
