Upper primary school mathematics question UPQ114
The ratio of the length of a rectangle to its breadth is 7 : 2. The perimeter of the rectangle is 36 cm. Find its breadth.
The perimeter of a rectangle = Length + Length + Breadth + Breadth
Given the ratio of Length : Breadth = 7 : 2
The ratio of Length : Breadth : Perimeter = 7 : 2 : 18
18 units = 36cm
1 unit = 2cm
The Breadth of the triangle = 2 × 2 = 4 cm
