The exterior wall (the gabled end of the house shown) remains to be painted.
a) What is the area of the outside wall?
b) If each gallon of paint covers approximately
c) If each gallon of paint is on sale for $22.50, what is the total cost of the paint?
a)
The area of the outside wall.
1) Procedure:
Finding the area of the figure is followed by identifying the figure and find area with the suitable geometry formulae.
2) Calculation:
Given,
In a given figure, the wall is a compound figure of triangle and rectangle.
Where,
Length of rectangle
Width of rectangle
Base of the triangle
Height of the triangle
Area of a rectangular wall
b)
The gallons of paint must be purchased if each gallon of paint covers
c)
The total cost of paint, if each gallon of paint is on sale for $22.50
