How do you calculate surface area for trapezoidal prisms

Lateral Surface Area.

Step 1 : Find the perimeter of the trapezoidal base by adding measures all four sides together.

Step 2 : Determine height of the prism.

Step 3 : Calculate the product of both quantities. It gives required lateral surface area.

Step-by-step explanation:

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'.
