Answer: $\dfrac{729}{4}\ in.^2$

Step-by-step explanation:

Given

length of each patch is $2\ \frac{1}{4}$ in.

The size of the quilt is $6\times 6$ array i.e. there are $6^2$ patch available

The area of each patch is

$\Rightarrow \dfrac{9}{4}\times \dfrac{9}{4}\\\\\Rightarrow \dfrac{81}{16}\ in.^2$

The area of the whole quilt is

$\Rightarrow 36\times \dfrac{81}{16}\\\\\Rightarrow \dfrac{729}{4}\ in.^2$

Length of DA: 90°
They are placed on a obtuse angle, which is 180° and DA are also placed on a right angle, so that means 180°-90°=90°

Length of AB: 180°
Their placed on a obtuse angle, therefore it will just be 180°

ADF=BDE because, both of them are right angles. This means their degrees will equal (90°=90°).

Hopefully this helps, sorry if I turn out to be wrong!

dolphi86 [110]

Related diagram is attached below :

Answer:

Step-by-step explanation:

The height, h of the tent attached below can be obtained using Pythagoras rule, as the shape forms a right angle triangle.

Length of base , = 24 / 2 = 12 feets

Hypotenus = 15 feets

The height, h = √(hypotenus² - Base²)

h = √15² - 12²

h = √225 -144

h = √81

h = 9 feet

Tent shouldn't be rented as it is below 10 feets
