Question

The perimeter of the closed shape PQRS given below is 47 1/2 cm.

Answer 1

Answer:

$perimeter \: = \: sum \: of \: all \: sides \: \\ so \: let \: qr \: be \: x \\ x + 13 + 10 \times \frac{5}{8} + 14 \times \frac{3}{4} = 47 \times \frac{1}{2} \\x + 13 + \frac{85}{8} + \frac{59}{4} = \frac{94}{2} \\ x + \frac{104 + 85 +118}{8} = \frac{94}{2} \\ x + \frac{307}{8} = \frac{94}{2}$
