the length of PQ is 33 cm
Explanation:
The perimeter of the triangle = 94 cm
The triangle is an isosceles triangle as two of its sides are equal
From the diagram:
PQ = RQ
Perimeter of triangle = PQ + PR + RQ
PR = 28 cm
94 = PQ + 28 + RQ
94 = 2PQ + 28
94 - 28 = 2PQ
66 = 2PQ
divide both sides by 2:
66/2 = 2PQ/2
PQ = 33
Hence, the length of PQ is 33 cm
