Question

Hi I just need quick answers !

Answer 1

Question 1: Perimeter of base

• Definition of Perimeter: is the of the side lengths

         ⇒ Perimeter = 10 + 10 + 10 + 10 = 40 ft

Question 2: Find the slant height

• Definition of Slant Height:  is the distance measured along a lateral face from the base to the center along the "center" of the face

        To understand the slant height, look at the diagram I attached

       Slant height: 13 ft

Question 3:  Find the Lateral Area

• Definition of Lateral Area: Area of the non-base faces only

         ⇒ Lateral Area = 4 * (Area of Triangle)

                                    = $4*(\frac{1}{2} *10 * 13) = 4 * 5* 13 = 260ft^2$

                                    = 260 ft^2

Question 4: Area of Base

       Area of Base = 10 * 10 = 100ft^2

Question 5: Surface Area

• Definition of Surface Area: sum of the areas of surfaces of the figure

        Surface Area = Area of Base + Lateral Area

                               = 100 + 260 = 360 ft^2

Hope that helps!
