please give right answer if the answer is right I will mark as brainlist​

Answer 1

Answer:

• Area of Rectangle is 120cm²

Step-by-step explanation:

According to the Question

It is given that ,

• Dimensions of rectangle 12cm×10cm

we have to calculate the area of rectangle.

we know that

Area of Rectangle = Length ×Breadth

On substituting the value we get

↠Area of Rectangle = 12×10

↠ Area of Rectangle = 120cm²

• Hence, the area of rectangle is 120cm².

Answer 2

Answer:

Question :-

• What is the area of rectangle of dimensions 12 cm × 10 cm.

Correct Options :

◆ a) 44 cm²

◆ b) 120 cm²

◆ c) 1440 cm²

◆ d) 1200 cm²

Given :-

• A rectangle whose length is 12 cm and breadth is 10 cm.

To Find :-

• What is the area of a rectangle.

Formula Used :-

$\clubsuit$ Area Of Rectangle Formula :

$\small \bigstar \: \: \sf\boxed{\bold{Area_{(Rectangle)} =\: Length \times Breadth}}\: \: \: \bigstar$

Solution :-

Given :

• Length = 12 cm
• Breadth = 10 cm

According to the question by using the formula we get,

$\small \implies \sf\bold{Area_{(Rectangle)} =\: Length \times Breadth}$

$\implies \sf Area_{(Rectangle)} =\: 12\: cm \times 10\: cm$

$\implies \sf Area_{(Rectangle)} =\: (12 \times 10)\: cm^2$

$\implies \sf Area_{(Rectangle)} =\: (120)\: cm^2$

$\implies \sf\bold{\underline{Area_{(Rectangle)} =\: 120\: cm^2}}$

$\therefore$ The area of a rectangle is 120 cm² .

Hence, the correct options is option no (b) 120 cm² .
