Answer:

6) a) 15 inches

7) b) 4 cm

The side of the square 4 cm

8) C)

Area of the square = side ×side

Step-by-step explanation:

<u><em> Step(i):-</em></u>

Given that the perimeter of the square is twice the perimeter of the triangle

we know that the perimeter of the square = 4a and

The perimeter of the triangle = a+b+c

Given that the perimeter of the square is twice the perimeter of the triangle

             4a = 2( a+b+c)

             2a = 11 +9+10

             2a = 30

               a =15

The side of the square = 15 inches

<u><em>Step(ii):-</em></u>

<em>7) </em>

Given that the area of the square is equal to the area of the rectangle

         a² = length × breadth

        a²  = 8×2 =16

       a= √16

      a = 4cm

8)

Area of the square = side ×side

find the numerical lengths of the diagonals of the parallelogram below where FB=4x-2 FD=3y-1 FC=3x and FA=3y-3. solve using a sy
Andre45 [30]

Answer:

BD = 28

AC = 24

Step-by-step explanation:

Diagonals of a parallelogram bisect each other.

4x − 2 = 3y − 1

3x = 3y − 3

Using elimination to solve the system of equations, subtract the second equation from the first.

(4x − 2) − 3x = (3y − 1) − (3y − 3)

4x − 2 − 3x = 3y − 1 − 3y + 3

x − 2 = 2

x = 4

Substitute into either equation to find y.

3(4) = 3y − 3

12 = 3y − 3

15 = 3y

y = 5

The length of BD is:

4(4) − 2 + 3(5) − 1 = 28

The length of AC is:

3(4) + 3(5) − 3 = 24
