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:

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

Area of the square = side ×side

Answer:

Step-by-step explanation:

This is not a linear relationship, it doesn't have a set increase or uniform slope and it seems more like an exponential or quadratic curve to me when I graph it. As you can see you cant draw a straight line through the data points so it cannot be a linear relationship.
