Question

The diagram shows a floor in the shape of a trapezium. Tim is going to paint the floor. Each 5 litre tin of paint costs £16.99 and 1 litre of paint covers an area of 1.9 m2 How much would it cost to buy all the paint he needs? You must show how you get your answer. 0 m 16m £16.99

Answer 1

Answer: £186.89

Step-by-step explanation:

-We are given that each 5l  tin of paint costs £16.99 . We therefore divide the paint used by 5 and multiply by £16.99:

Hence, it will cost £186.89 to buy all the paint

Answer 2

Answer:

=£186.89

Step-by-step explanation:

A=1/2(a+b)h

a||b dimensions

A=1/2(16+10)×7.6

=98.8m²

Given that 1 litre of paint covers an area of 1.9 sq m, we divide the area of the trapezium by this and multiply by the price per liter to get total cost:

paint used= Area/paint m²

98.8/1.9

=52 litres

We are given that each 5l  tin of paint costs £16.99 . We therefore divide the paint used by 5 and multiply by £16.99

52/2

=10.4

11tins

cost=11×16.99

=£186.89
