2 units = 28cm

1 unit = 28cm ÷ 2 = 14cm

PQ = 3 units = 14cm x 3 = 42cm

Or

If breadth is ⅔ of length, then length is 3/2 of breadth.

So PQ = 14cm x 3/2 = 42cm

TU = 1/6 of PQ

= 1/6 x 42cm

= 7cm

Height of shaded triangle

= 28cm - TU

= 28cm - 7cm

= 21cm

Area of shaded triangle

= ½ x base x height

= ½ x 42cm x 21cm

(since base is same as length of rectangle)

= 441cm²

Area of rectangle

= Length x breadth

= 42cm x 28cm

= 1176cm²

Unshaded area

= Area of rectangle - area of shaded triangle

= 1176cm² - 441cm²

= 735cm²
