The diagram shows a floor in the shape of a trapezium.
10 m
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 m(squared)
How much would it cost to buy all the paint
he needs?
You must show how you get your answer.
Total marks: 5

£186.89

Step-by-step explanation:

-The area of the trapezium can be calculated as follows:

-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:

-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

*Paint is only bought in 5l tins. Hence, any fractional bit will necessitate the purchase of the whole 5l tin

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
