Answer:

The perimeter and area of the square are 56 units and 196 square units, respectively.

Step-by-step explanation:

The inner right triangle represents a 45-45-90 right triangle, which has the feature of a hypotenuse whose length is \sqrt{2} time the length of any of its legs. If the hypotenuse has a measure of 7\sqrt{2}, then the legs of the triangle have a measure of 7.

Now, we are aware that the side length of the square is twice the length of the leg of the right triangle. Then, side length of the square is 14 units long.

Lastly, we know from Geometry that the perimeter and area of the square are represented by the following expressions:

Perimeter

p = 4\cdot l (1)

Area

A = l^{2} (2)

Where l is the side length of the square.

If we know that l = 14, then the perimeter and area of the square are, respectively:

p = 4\cdot (14)

p = 56

A = 14^{2}

A = 196

The perimeter and area of the square are 56 units and 196 square units, respectively.

Susan is buying supplies for a party. If spoons only come in bags of 8 and forks only come in bags of 6, what is the least numbe
igor_vitrenko [27]
You can buy 6 bags of forks and 8 bags of spoons. All you simply have to do is find the common multiple of the two. You can just multiply them both if you can’t find any others or it’s easier

Divide 128 by 16 to get how many balloons will go on each post.

128 ÷ 16 = 8

8 balloons per post :)
