If a 4 x 16 rectangle has the same area as a square, what is the length of a side of the square?

Licemer1 [7]

Answer:

Option D. 8 units

Step-by-step explanation:

step 1

Find the area of rectangle

The area of rectangle is

$A=(4)(16)=64\ units^2$

step 2

Find the length side of the square with the same area of rectangle

The area of a square is

$A=b^2$

where

b is the length side of the square

we have

$A=64\ units^2$

substitute

$64=b^2$

take the square root both sides

$b=8\ units$

therefore

The length side of the square is 8 units

I need help please and thank you.

kogti [31]

Step-by-step explanation:

$\frac{2x}{5} + \frac{1}{3} = \frac{7x - 2}{15}$

$\frac{6x + 5}{15} = \frac{7x - 2}{15}$

$6x + 5 = 7x - 2$

$6x - 7x = - 2 - 5$

$- x = - 7$

$x = 7$
