Answer 2

Answer:

Given, a parallelogram land,

Consider a parallelogram ABCD, adjacent sides are given, AB=13m

BC=15m

And diagonal AC=14m

Semi perimeter of ∆ABC, S =

S= 21m

Hence area of ∆ABC =

sq. m

Area ∆ABC = 84 sq. m

Area of parallelogram ABCD = 2×area of ∆ABC

Area of parallelogram ABCD = 2×84

= 168 sq. m
