**Upper primary school mathematics question UPQ567**

Sarin used some rectangle papers to create below figure.

The rectangle papers are identical and the length is 3 time of the breadth.

If the total area of the figure was 648 m^{2}, what was the length of the rectangle paper?

Solution:

Total area of the figure = 648 cm^{2}

There were 6 number of rectangle papers,

The area of one rectangle paper = 648 ÷ 6 = 108 cm^{2}

The length of the rectangle is 3 times of the breadth of the rectangle,

One square unit = 108 ÷ 3 = 36 cm^{2}

Area = B × B = 36

The breadth, B = 6 cm

The length, L = 3 × 6 = __18 __cm
