Question

if one side of a rectangular field is18m long and one of its diagonals is 30m ,then the area of the field in square meter is

Answer 1

Answer:

432m²

Step-by-step explanation:

let rect.be ABCD and diagonals be AC

AC=30m

BC=18m

AB=?

AB²+BC²=AC²

AB²+18²=30²

AB²=30²-18²

AB=√900-√324

AB=√576

AB=24

length=18m

breadth=24m

therefore area of field=432m²
