Answer:
120m
Step-by-step explanation:
one side of rectangle=15m
diagonal = 17m
by pythagoras theorem.....(all angles of rectangle
are 90°)
so, (17)2 = (15)2 + square of second side
289 =225 + square of second side
square of second side = 289 - 225
=64
length of second side = 8 cm ...( taking square root).
area of field = l × b
=15×8
= 120 M.
THE AREA OF FIELD IS 120M.
