Let the side of  one square be x.    Area = x*x = x²

Then the side of other square  would be 2x ,   Area = 2x*2x = 4x²

Combined area = x² + 4x²  = 5x²

This combined area = 45 cm²

Therefore  5x²  = 45   Divide both sides by 5
                  x²  =  45/5
                  x²  = 9        Take square root of both sides
                  x   =  √9
                  x  = 3

Length of larger square is 2x  = 2*3 = 6 cm
Length of larger square = 6cm

How many sides would there be in a convex polygon if the sum of all but one of its interior angles is $1070^{\circ}$
Gwar [14]

Convex Polygon:

A polygon is called a convex polygon when no line segments between the points, goes inside. The boundaries of the convex polygon do not go inside and all the vertices are pointed outside away from the center. The interior angles of a convex polygon are less than 180°.

Lets simplify the given problem,

If we try using 1070 degrees as the sum of the interior angles of a convex polygon, we get:

1070 =[n - 2] x 180, where n = number of sides

1070 =180n - 360180n =1070+360180n =1430n = 1430 / 180

n = 7.94 number of sides. Since this is not a whole number, will simply round it up to 8.

Hence the number of sides is 8

k0ka [10]

  • <em>I am assuming the picture is of a stained glass window in the shape of a semicircle</em>.

Answer: 7.71 feet.

Step-by-step explanation: <em>The formula for finding the circumference of a circle is \frac{1}{2} π × d + d.</em>

The diameter is 3 feet. Substitute this into the equation:

\frac{1}{2} π × 3 + 3.

Solve -

3.14 × 3 = 9.42

\frac{1}{2} of 9.42 = 4.71

4.71+3 = 7.71

Round -

The answer is already rounded.

Hope this helped!~
