Answer:
the correct answer is 120 square meters
Step-by-step explanation:
DG is a half diagonal and it intersects with the other diagonal at 90°. So it forms a right angle triangle. Using Pythagoras theorem
13^2-5^2=d^2
169-25=d^2
144=d^2
d=√144
d=12
so the other half diagonal is 12m
the two diagonals will be 2×5 and 2×12
the two diagonals will be 10m and 24m
area of a rhombus=1/2d1d2
area of the rhombus= 1/2×10×24
area of the rhombus=120 square meters
