Answer: it’s 88 units squared 60 units squared and 148 units squared

Step-by-step explanation: your trying to look for the bases that are shaded and trying to find the lateral area area of two bases and total surface area

Answer:

Part 1) The lateral area is
LA=88\ units^2

Part 2) The area of the two bases together is
2B=60\ units^2

Part 3) The surface area is
SA=148\ units^2

Explanation:

Part 1) Find the lateral area

we know that

The lateral area of a prism is given by


LA=Ph

where

P is the perimeter of the base

h is the height of the prism

so


P=2(6+5)=22\ units ----> perimeter of rectangle


h=4\ units ---> given

substitute


LA=22(4)=88\ units^2

Part 2) The area of the two bases together is?

The area of the rectangular base B is equal to


B=(6)(5)=30\ units^2

therefore

The area of the two bases together is


2B=2(30)=60\ units^2

Part 3) The total surface area is

we know that

The surface area is equal to


SA=2B+LA

substitute


SA=60+88=148\ units^2
