GOT ANOTHERONE DUE IN 6 MIN PLEASE HELP FAST!!!!!!!!!!!!!!!!!!!!!

Answer 1

✰Given:-

➾Length(L) of bigger rectangle = $\sf{9+3\: =\:12}$units.

➾Length(l) of smaller rectangle = 9units.

➾Breadth (B) of bigger rectangle = $\sf{4+4 \:=\: 8}$units.

➾Breadth(b) of smaller rectangle = 4 units.

✰To Find:-

➾Area of the shaded region.

✰Solution:-

➾We can find the area of shaded region by subtracting area of smaller rectangle from area of bigger rectangle(that is whole rectangle including shaded and non shaded region).

So,

➾Area of bigger rectangle = $\sf{L×B}$(putting the value of L and B from the above given)

= $\sf{8×12}$

= $\sf{96unit^2}$

Similarly,

➾Area of smaller rectangle = $\sf{l×b}$(putting the value of l and b from the above given)

= $\sf{9×4}$

= $\sf{36unit^2}$

Now,

➾Area of shaded region = Area of bigger rectangle - Area of smaller rectangle.

$\sf{= 96-36}$

$\sf{= 60unit^2.}$

Therefore, area of shaded region$\sf{= 60unit^2.}$

Answer 2

$\bold{\huge{\underline{ Solution }}}$

Given :-

• We have given one rectangle whose 3 by 4th part is shaded and remaining part is non shaded.

To Find :-

• We have to find the area of shaded region of the given figure .

Let's Begin :-

Here, We have

• The dimensions of large rectangle as 12 units and 8 units
• That is,
• $\sf{ Length = 9 + 3 = 12 \: units}$
• $\sf{ Breath = 4 + 4 = 8 \: units}$
• The dimensions of non shaded rectangles are 9 units and 4 units

We know that,

Area of rectangle

$\bold{\red{ = Length {\times} Breath }}$

Subsitute the required values,

Area of large rectangle

$\sf{ = 12 {\times} 8 }$

$\sf{ = 96 \:units^{2}}$

Thus, The area of large rectangle is 96 units² .

Now,

Area of non - shaded rectangle

$\sf{ = 9 {\times} 4 }$

$\sf{ = 36\: units^{2}}$

Thus, The area of non shaded rectangle is 36 units² .

Therefore,

Area of shaded region

= Area of large rectangle - Area of non shaded rectangle

Subsitute the required values,

$\sf{ = 96 - 36}$

$\sf{ = 60\: units^{2}}$

Hence, The total area of shaded region is 60 sq.units.
