In square PQRS if PQ=(3x−7) units and QR=(x+3) units, Find PS.
10 units
8 units
6 units
12 units
Sides of a square are equal.
PQ=QR
⇒3x−7=x+3
⇒3x−x=3+7
⇒2x=10
⇒x=5
⇒PS=QR=x+3=5+3=8 units
Find the area of quadrilateral ABCD in sq.units, given AE = 10 units, BD = 24 units and CF = 8 units.
ABCD is a rectangle. If OB = x + 2 and AC = 5x - 2, then find the measure of AC.
