This trapezium is drawn on a centimetre grid.<br> Find the area of the trapezium.

aivan3 [116]

Answer:

20 unit²

Step-by-step explanation:

A trapezium is given to us on the grid and we need to find out the area of the trapezium . In order to find the area , we need to find the measure of the parallel sides and the distance between the parallel sides.

<u>From </u><u>the</u><u> </u><u>grid</u><u> </u><u>:</u><u>-</u>

$\rm\implies Side_1 = 7 \ units$

$\rm\implies Side_2 = 3 \ units$

$\rm\implies \perp \ Distance =4 \ units$

Now here we got the two parallel sides of the trapezium and the distance between the two parallel sides. Now we can find the area as ,

$\rm\implies Area_{Trapezium}= \dfrac{1}{2}\times ( s_1 + s_2) \times \perp \ Distance \\\\\rm\implies Area = \dfrac{1}{2} \times ( 7 + 3 ) \times 4 \ unit^2 \\\\\rm\implies Area = \dfrac{1}{2} \times ( 10) \times 4 \ unit^2 \\\\\rm\implies\boxed{\rm Area = 20 \ unit^2}$

The floor plan shows an l shaped room. Shane wants to buy carpet for the room. The cost for one square foot of carpet is $4. Wha

VashaNatasha [74]

The area of shape is the amount of space on it.

The cost to carpet the room is $224

From the floor plan (see attachment), we can divide the room into two shapes:

<em>A 8ft by 6ft rectangle</em>
<em>A 4ft by 2ft rectangle</em>

<em />

So, the area of the floor plan is:

$\mathbf{Area = 8ft \times 6ft + 4ft \times 2ft}$

$\mathbf{Area = 48ft^2 + 8ft^2}$

$\mathbf{Area = 56ft^2}$

The unit cost of carpet is <em>$4 per one square foot </em>

So, the cost to carpet the room is:

$\mathbf{Cost = \$4 \times 56}$

$\mathbf{Cost = \$224}$

Hence, the cost to carpet the room is $224
