Find the perimeter and the area of the figure. I have been trying to figure this one out for hours.

56 meters

Step-by-step explanation:

when calculating the perimeter, you need to take into account every side of the figure.

i will start at the top and go clockwise showing you my calculations

5 + 5 + 11 + 7 + 16 + 7 + 5

= 56

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'.
