Question

find my length and breadth from the given information.​

Answer 1

Step-by-step explanation:

In a rectangle, the opposite sides are equal.

Therefore, x+7 = y+8

x = y + 1              ( equation 1)

Now for breadths,

x+y = 3x - 2y

⇒2x - 3y = 0               (equation 2)

Now we can replace x in equation 2 with the value we got from equation 1.

∴ 2( y + 1 ) -3y = 0

2y + 2 - 3y = 0

-y + 2 = 0

∴ y = 2

∴ x =  y + 1   = 3

∴ length = 3+7 = 10units

breadth = 2 + 3 = 5 units
