The area of a square can be found using the equation a = s², where a is the area and s is the measure of one side of the square.

match the equation for how to solve for the side length of a square to its description.

a square has an area of 144 in^2

choices: s=144in

s=144^2in

s= √144in (squared, incase no one knew)

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
