Question

give me answer of 11

Answer 1

let x be the common multiple
first parallel side = 4x
second parallel side = 7xq
Area of trapezium=1/2(P1+P2)×h
$385 = \frac{1}{2} (4x + 7x) \times 14 \\ 385 = 11x \times 7 \\ 385 = 77x \\ x = \frac{385}{77} \\ x = 5m$
first parallel side = 4×5= 20m
second parallel side = 7× 5 = 35m
Hope this helps you :-))))
