Question

In a square ABCD if ab is equal to 3 x- 8 centimetre and BC is equal to x + 6 coma find the value of x also find the length of each side of the square

Answer 1

Answer:

x = 7

length of side = 13cm

Step-by-step explanation:

in square ABCD all sides are equal

AB = BC = CD = AD

AB = 3x - 8

BC = x + 6

therefore

3x - 8 = x + 6

3x - x = 6 + 8

2x = 14

x = 14/2 = 7

therefore Side of square is

3x - 8 = 3(7) - 8 = 21 - 8 = 13cm
