Please help me to solve these with explanation ​

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:

Step(i):-

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

Step(ii):-

7)

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)
