7. If the area of a square is 64 square centimeters, what's the
Anvisha [2.4K]

Answer:

If you're asking what the perimeter is:

C 32cm

If you're asking what the length of a side is:

A 8cm

Step-by-step explanation:

Area of a square is calculated by length x width.

And all four sides of a square are equal in length.

Area: 8cm×8cm=64cm2

Perimeter: 8cm + 8cm + 8cm + 8cm= 32cm

Another way to find the length of the sides would be to take the square root of 64. I believe that only works with the area of a square though.

√(64)=8

Given the measure of three angles in a quadrilateral, find the measure of the fourth angle.1. 40 degree , 120 degree , 100 degre
Veronika [31]

Recall that the interior angles of a quadrilateral add up to 360 degrees.

1) Let x be the measure of the missing angle, then we can set the following equation:

40^{\circ}+120^{\circ}+100^{\circ}+x=360^{\circ}.

Solving for x we get:

\begin{gathered} 260^{\circ}+x=360^{\circ}, \\ x=100^{\circ}\text{.} \end{gathered}

2) Let y be the measure of the missing angle, then we can set the following equation:

73^{\circ}+107^{\circ}+122^{\circ}+y=360^{\circ}\text{.}

Solving for y we get:

\begin{gathered} 302^{\circ}+y=360^{\circ}, \\ y=58^{\circ}\text{.} \end{gathered}

Answer:

1) 100 degrees.

2) 58 degrees.
