You buy the following materials for the new extension. Calculate the cost of the bricks and cement and then work out the total c
bogdanovich [222]

<u>Answer:</u>

Cost of sand = £150

Cost of bricks =  £157.5

Cost of cement = £134

Total cost = £441.50

<u>Step-by-step explanation:</u>

We are given that:

2 tonnes of sand  is for £75.00 per tonne,

20 bags of cement  are for £6.70 per bag,

350 bricks at 45p each,

So, 2 tonnes of sand  at £75.00 per tonne = 2 * £75.00 = £150.00

20 bags of cement  at £6.70 per bag = 20 * £6.70 = £134.00

350 bricks at 45p each = 350 * £0.45 = £157.50

Therefore, the total cost of all the materials = £150 + £134 + £157.5 = £441.50

The length of a rectangle is 4 more than 3 times the width if the perimeter of the rectangle is 18.4 cm what is the area of the
garik1379 [7]
Let's call the width: w

the lenght is then 3w+4 ("4 more than 3 times the width")

and the parameter would be 2(w+3w+4), that is 2*(4w+4), that is 8w+8.

this is also equal to 18.4:

8w+8=18.4
8w=10.4
w=1.3

this is the width, and the lenght is:
4+3*1,3=4+3.9=7.9

and the area is their product:
1.3*7.9=10.27
