The length of the straight line PQR is 22 cm. If PQ : QR m = 4: 7, find the length of PQ.

Find the length of PQ and PR,

If the length of the side PQ of the rhombus PQRS is 6 cm and anglePQR = 120^(@) , then the length of QS, in cm, is

PQRS is a parallclogram such that PQ is parallel to SR and SP is parallel to RQ. The length of side PQ is 20 cm. M is point between P and Q such that the length of PM is 3 cm. N is a points between points S and R. Find the length of SN such that segmen MN divides the paralelogram in two regions with equal areas.

PQRS is a straight line. PQ = 2 cm and PS = 40 cm. If PR : RS = 7 : 3, then QR in cm is:

In fig , a circle isinscribed in a triangle PQR with PQ = 10 cm , QR = 8 cm and PR = 12 cm .Find the length of the QM , RN and PL.

PQRS is a common diameter of three circles. The area of the middle circle is the average of the area of the other two. If PQ = 2 and RS = 1 then find the length QR

Given PQR is a straight line and PQ : QR = 37. Find QR : PQ
