Question

The perimeter of the given triangle is ______cm
a)4x + 8y - 3
b)3x + 4y - 3
c)4x - 8y - 3
d)4y + 8x - 3

Answer 1

Answer:

The correct answer of the question is a) 4x + 8y - 3.

Step-by-step explanation:

The perimeter of a triangle is equal to the sum of its three lengths.

Thus P= AB + BC + AC

P= ( 10y-2x) cm + ( 2x-2y-1) cm + (4x-2) cm

= 10y - 2x + 2x - 2y - 1 + 4x - 2

= 4x -2x +2x +10y -2y -1 -2

= 4x + 8y - 3

Hope it helps.

Answer 2

Answer:

c is the ans

Step-by-step explanation:

10 y - 2x cm or (2x - 2y -1) cm or (4x -2) =

10 y- 2x or 2x - 2y - 1 or 4x -2 =

10 - 2 ,or 2 - 2 -1 or 4 - 2 =

10 - 2 = 8

2-2-1 = - or - = + so ,= 2+2+1 =5

4 - 2 = 2

8 + 5 + 2 = 15 or 8-5 - 2. = 1 =

15 +1 = 16 and half of 16 = 8 half of 8 = 4

so ans is 4 x - 8y - 3=

(c )
