One side of rectangular field is 15 meter and one of its diagonals is 17 meter.
Question 1:
One side of rectangular field is 15 meter and one of its diagonals is 17 meter. Then find the area of the field.
A.
120m^2
Feedback
We know h^2=b^2+h^2
Other side =√(17)^2−(15)^2 =√64=8mtr
Area=Length×Breadth
=15×8m^=120m^2
B.
130m^2
C.
140m^2
D.
150m^2
