The cost of total paint is 176.696
Step-by-step explanation:
Given,
The length of two parallel lines (l and b) are 10 m and 16 m
Height (h) = 7.6 m
Cost of 5 l paint is 16.99
1 l of paint covers 1.9 m²
To find the cost of paint to cover the floor.
Formula
The area of the trapezium is = (l+b)h
So,
The area of the floor = (16+10)×7.6 m²
= 98.8 m²
Again,
1.9 m² will be covered by 1 l of paint
1 m² will be covered by l of paint
98.8 m² will be covered by l of paint
= 52 l
Now,
5 l of paint cost = 16.99
1 l of paint cost =
52 l of paint cost = = 176.696
Hence,
The cost of total paint is 176.696

In step 1, Deepak rearranged the terms in order to simplify like terms together that is followed in step 2.
o, rearranging of the terms of an expression is commutative property and not distributive property. The distributive property is generally applicable to multiplication and is given as:
The commutative property is given as:
x+y = y +a
Therefore, adding terms by changing their order is commutative property of addition and not distributive property. Step 1 instruction is wrong.
