Question

Jacob wants to paint a wall of dimensions 15 feet by 8 feet. If the cost of painting 1 sq. foot of the wall is $ 5 , then the total cost of painting the wall will be the amount of money

Answer 1

Given :

Dimensions of the wall ⇢ 15ft x 8ft

To find :

Total cost of painting the wall if the cost of painting 1 sq. foot of the wall is $5

Solution:

To find the cost of painting the wall ,

we'll firstly find the area of the wall then multiply it by the given cost per sq. foot

Area of the wall⇢ Product of it's dimensions

Area of the wall⇢ 15ft x 8ft

Area of the wall ⇢120ft²

Given that ,

cost of painting 1 sq. foot of the wall ⇢ $5

so,

cost of painting 120 sq.foot of the wall ⇢120 x $5

cost of painting 120 sq.foot of the wall ⇢ $ 600

hence,the total cost of painting the wall will be

$600
