RRB Group-D Model Paper 18 with answers for online practice

As we see in the figure,
Let the length of the rectangle be a m and breadth of the rectangle be b m.
According to problem,
⇒ a – b = 27 ----(1)
And, 2(a + b) = 214
⇒ a + b = 107 ----(2)
From (1) and (2) we get,
⇒ a = 67 and b = 40
∴ The area of the rectangle = 67 × 40 = 2680 m2
