Question

The length of the fence of a trapezium-shaped field ABCD is 130 m
and side AB is perpendicular to each of the parallel sides AD
and BC. If BC = 54 m, CD = 19 m and AD = 42 m, find the area of
the field.​

Answer 1

Step-by-step explanation:

The perimeter of field is 130

⟹AB+BC+CD+AD=130

AB=130−54−19−42

AB=15m

Area is given as

1

AB(AD+BC)
