a man buys 11 lemons for 10 rupees and sells 10 lemons for 11 rupees.what is his gain %​

Answer:

.

CD∥AB

∴ CD∥AE [ Extended part of parallel side ]

⇒ Area of parallelogram ABCD=AB×CE [ Since, CE situated between same parallel lines ]

=12×6.2

=744cm

2

---- ( 1 )

⇒ Area of a parallelogram ABCD=AD×BF

=8×BF ----- ( 2 )

Comparing ( 1 ) and ( 2 ) we get,

⇒ 8×BF=744

⇒ BF=

8

744

=93cm

∴ The area of parallelogram ABCD is 744cm

2

and the length of BF

Answer:

93

Explanation:

Predecessor means the before number and 94 before number is 93

Answer:

[tex]\huge\color{red}\boxed{\colorbox{orange}{81 cm²}}[/tex]

Step-by-step explanation:

The given shape is square.

Square has only length.

Different shapes have different areas.

Formula for Area of Square:

[tex]\rightarrow[/tex][tex]\textsf{Length × Length= Length²}[/tex]

[tex]\textsf{Use Formula}[/tex]

[tex]\implies[/tex][tex]\textsf{(9 × 9)cm²}[/tex]

[tex]\textsf{Simplify}[/tex]

[tex]\implies[/tex][tex]\textsf{(81)cm²}[/tex]

[tex]\mathtt{Final \: Answer}[/tex]

Hence, the area is 81 cm²

Answer:

Let the length of the rectangle be x units and the breadth be y units.

Area of the rectangle=length×breadth

=x×y=xy sq. units

From the given information, we have,

(x+2)×(y−2)=xy−28

and(x−1)×(y+2)=xy+33

(x+2)×(y−2)=xy−28

=>xy−2x+2y−4=xy−28

=>−2x+2y=−24

=>−x+y=−12

=>x=y+12....(i)

Also,(x−1)×(y+2)=xy+33

=>xy+2x−y−2=xy+33

=>2x−y=35....(ii)

Substituting equation (i) in equation (ii), we get,

2x−y=35

=>2(y+12)−y=35

=>2y+24−y=35

=>y=11

Substituting y=11 in equation (i), we get,

x=y+12

=>x=11+12

=>x=23

Therefore, length of rectangle =x=23 units

and breadth of rectangle =y=11 units

Area of rectangle =xy=23×11=253 square units
