Question

Find the perimeter, as indicated

Width Length Perimeter Area

w 1.5w _________cm 294cm²

Answer 1

Area: w * 1.5w = 1.5w² = 294. Divide both sides by 1.5, so w² = 196, and w = 14.

therefore width = 14, length = 1.5 * 14, so length = 21.

perimeter = 2*width + 2*length, so 2*14 + 2*21. Perimeter = 70 cm.
