Question 1 of 5

Find the area of the Trapezium

$\text(Area )=$ (45) $m^2$

Question 2 of 5

If the area of the Rhombus is

$400 cm^2$ and the diagonal

$BD$ is

$50 cm$ , find the length of the diagonal

$AC$

$AC=$ (16) $cm$

Question 3 of 5

Find the area of the Trapezium

$\text(Area )=$ (110) $cm^2$

Question 4 of 5

4. Question
Find the area of the Parallelogram
- $\text(Area )=$ (459) $cm^2$
Correct

Well Done!

Incorrect

Area of a Parallelogram Formula

$\text(Area )=$ $\text(base)$ $times$ $\text(height)$

Identify the known lengths

$\text(base)=17$

$\text(height)=27$

Solve for the area using the Area of a Parallelogram formula

$\text(Area)$ $=$ $\text(base)$ $times$ $\text(height)$ Area of a Parallelogram formula

$=$ $17$ $times$ $27$ Plug in the known lengths

$=$ $459 cm^2$

$\text(Area)=459 cm^2$
Question 5 of 5

5. Question
Find the area of the Kite
- $\text(Area )=$ (16) $m^2$
Correct

Correct!

Incorrect

Area of a Kite Formula

$\text(Area)= 1/2 times$ $\text(base)$ $times$ $\text(height)$

Identify the known lengths

$\text(base)=4$

$\text(height)=8$

Solve for the area using the Area of a Kite formula

$\text(Area)$ $=$ $1/2 times$ $\text(base)$ $times$ $\text(height)$ Area of a Kite formula

$=$ $1/2 times$ $4$ $times$ $8$ Plug in the known lengths

$=$ $16 m^2$

The given measurements are in metres, so the area is measured as square metres

$\text(Area)=16 m^2$

$\text(Area)$	$=$	$1/2 times$ $x$ $times$ $y$	Area of a Rhombus Formula

$400$	$=$	$1/2 times$ $50$ $times$ $y$	Evaluate

$400$	$=$	$25 times y$

$400$ $divide 25$	$=$	$25 times y$ $divide 25$	Divide both sides by $25$
$16$	$=$	$25$ $times y$ $divide 25$	$times 25 divide 25$ cancels out
$16$	$=$	$y$
$y$	$=$	$16 cm$
$AC$	$=$	$16 cm$	$y=AC$
