Answer:
120 square units
Step-by-step explanation:
In triangle PSQ, PS=SQ. Let PS=SQ=x units.
Since SQ-PQ=1, PQ=SQ-1=x-1 units.
The perimeter of the triangle PSQ is 50 units, so
PS+SQ+PQ=50 units.
Substitute PS=SQ=x un. and PQ=x-1 un.
x+x+x-1=50
3x=51
x=17
Hence
PS=SQ=17 units,
PQ=16 units.
Use Heron's formula to find the area:
where p is semi-perimeter and a,b,c are lengths of sides.
