What is the surface area of this wedge?

The surface of this wedge is 84 ft²

A is correct.

Step-by-step explanation:

First we split the wedge into different figure. Please see the attachment for figure name.

Here we have total five figure.

We will find the area of each part and then add all together to find surface area.

Area of triangle, (Part A)

Area of rectangle, (Part B)

Area of triangle, (Part C)

Area of triangle, (Part D)

Area of triangle, (Part E)

Surface Area = A+B+C+D+E

Surface Area = 6+18+6+24+30 = 84 ft²

Hence, The surface of this wedge is 84 ft²

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

x = 23.78
