The length of a rectangle is twice its breadth, If its length is decreased by 5 cm and breadth is increased by 5 cm, the area of the rectangle is increased by 75 sq. cm. Find the length of the rectangle?

ক) 20cm খ) 26cm গ) 30cm ঘ) 35 cm

ব্যাখ্যা (Explanation)

Suppose, Breadth is x cm; length will be 2x cm

so area = 2x2

If its length is decreased by 5 cm it will be 2x-5 and breadth is increased by 5 cm it will be x+5

New area will be (2x-5)(x+5) =2x2+ 10x - 5x - 25= 2x2+ 5x -25

So,

2x2+ 5x - 2x2 = 75

5x = 75

x = 13

Length is 26cm
