Question

one side of a rectangular field 12 m and its diagonal is15 m.find the area of rectangular


​

Answer 1

Answer:

108m²

Step-by-step explanation:

Let ABCD be the rectangle with AB=12m, and diagonal AC=15m

Then we will find the lenght of side adjacent to AB by pythagoras theorem.

AB²+BC²=AC²

12²+BC²=15²

144+BC²=225

BC²=81

BC=9m

So, area= AB×BC

             =12×9

             =108m²
