Question

a rectangular plot has a length of 21 metre and breadth of 17 metre find the perimeter and area of the plot​

Answer 1

Given:

✰ Length of Rectangular plot = 21m

✰ Breadth of Rectangular plot = 17m

To find:

✠ Area of Rectangular Plot.

✠ Perimeter of Rectangular Plot.

Solution:

Let's understand the concept first! In this problem, length and nreadth of a rectangular plot are given and we have to find the area and the perimeter of the rectangular plot. So we know that area of rectangular plot is given by length × breadth and perimeter of rectangular plot is given by 2(length + breadth).So let's put the given values in the respective formulas.

⟼ Area of Plot = Length × Breadth

⟼ Area of Plot = 21 × 17

⟼ Area of Plot = 357 m²

and,

⟼ Perimeter of Plot = 2(L + B)

⟼ Perimeter of Plot = 2(21 + 17)

⟼ Perimeter of Plot = 2 × 38

⟼ Perimeter of Plot = 76 m

∴ Area and Perimeter of the rectangular plot are 357 m² and 76 m respectively.

Answer 2

Given :

• Length of plot = 21m

• Breadth of plot = 17m

To Find :

• Area and perimeter

Solution :

✬ As in the question Lengthand breadth of the rectangular plot is given. so,Firstly we will find the area That is Length × Breadth, where Length is 21m and breadth is 17m. And Perimeter of Rectangle is 2 (Length + Breadth). By Putting the values in the formula we can easily find the area and perimeter of rectangular plot.

• ⇝ Length (L) = 21m

• ⇝ Breadth (B) = 17m

Area of Rectangle = L × B

⟶ Area of Rectangle = 21 × 17

⟶ Area of Rectangle = 357m²

____________________

Perimeter of Rectangle = 2 (L + B)

⟶ Perimeter = 2 ( 21 + 17)

⟶ Perimeter = 2 × 38

⟶ Perimeter = 76m

____________________

• Area of Rectangular Plot is 357m²

• Perimeter of Rectangular Plot is 76m
