Lower primary school mathematics question UPQ39
The figure below is made up of 3 identical rectangles.
a) Find the perimeter of the figure.
b) Find the area of the figure.
The three triangles are identical.
From the figure above,
The length of each rectangle = 3 + 3 = 6cm
The length of the figure = 3 + 6 = 9cm
The breadth of the figure = 3 + 3 = 6cm
The perimeter of the figure = 9 + 9 + 6 + 6 = 30cm
The area of the figure = 9 × 6 = 54cm2
