Question

The length and perimeter of rectangle are 12m and 300m find its area​

Answer 1

Answer:

138 m

Step-by-step explanation:

Length = 12m

Perimeter = 300m

Breadth = Perimeter/2 - Length

= 300/2 - 12

= 150 - 12

= 138 m

Hope it helps..!!

Answer 2

GIVEN :

• Length = 12m
• Perimeter = 300m

TO FIND :

• Breadth = ?
• Area of the rectangle = ?

STEP - BY - STEP EXPLANATION :

→ Length = 12m (Given)

→ Breadth = ?

→ Perimeter = 300m (Given)

$= > breadth = \frac{perimeter}{2} - length$

$= > breadth = \frac{300}{2} - 12$

$= > 150 - 12$

$= > \: breadth = 138m$

NOW, AREA OF THE RECTANGLE = ?

______________________________

★ Length = 12m

★ Breadth = 138m

=> Area = Length × Breadth

=> Area = 12m × 138m

=> Area = 1656m²

Hence, area of the rectangle = 1656m²
