Step-by-step explanation:

Length = 5x +4

Breadth = 4x-4

Perimeter = 2(L+B)

Perimeter :

$2(5x + 4 + (4x - 4)) \\ 2(5x + 4 + 4x - 4) \\ 2(5x + 4x + 4 - 4) \\ 2(9x) = 2 \times 9x$

$= 18x$

If the angles are 90,45,45 so the sides except hypotenuse are congruent
and the hypotenuse is equal to :
${6 \sqrt{2} }^{2} + {6 \sqrt{2} }^{2} = {x}^{2} \\ {8.5}^{2} + {8.5}^{2} = {x}^{2} \\ 72.25 + 72.25 = {x}^{2} \\$
${x}^{2} = 144.5 \\ x = 12$

the answer is 12

6 1/2 divided by 10 1/2

Schach [20]

Answer:

13/21

Step-by-step explanation:

Make 6 1/2 and 10 1/2 and improper fraction

6 1/2=13/2

10 1/2=21/2

K.C.F

Keep 13/2

Change the division symbol to multiplication

Flip 21/2 to 2/21

then multiply across

13*2=26

21*2=42

so the fraction is 26/42 and then simplify the fraction

13/21
