10.2.2 Perimeter and Area, PT3 Practice

Question 4: In diagram below, PQUV is a square, QRTU is a rectangle and RST is an equilateral triangle. The perimeter of the whole diagram is 310 cm. Calculate the length, in cm, of PV. Solution: PV=VU=TS=SR=QP Given perimeter of the whole diagram=310 cm PV+VU+UT+TS+SR+RQ+QP=310 PV+PV+50+PV+PV+50+PV=310 5PV+100=310  5PV=210    PV=42 cm Question 5: In diagram below, ABCD and CGFE are rectangles. M, G, … Read more
