Question

Find the breadth of a rectangular plot of land, if its area is 440 m² and the length is 22 m. Also find its perimeter.​

Answer 1

$\huge\underline\mathrm{SOLUTION:-}$

From the question it is given that,

• Area of the rectangular plot = 440 m²
• Length of the rectangular plot = 22 m

We know that:

• Area of the rectangle = Length × Breadth

440 = 22 × Breadth

Breadth = 440/22

Breadth = 20 m

Then:

Perimeter of the rectangle = 2(Length + Breadth)

= 2 (22 + 20)

= 2(42)

= 84 m

Therefore:

• Perimeter of the rectangular plot is 84 m.

Answer 2

Answer:

BREADTH=20

PERIMETER=84

Step-by-step explanation:

LET BREATH=X

THEN AREA=440 m²

AREA OF RECTANGLE=L*B

LENGTH=22 m

BY PUTTING IN FORMULA

22*X=440 m²

X=20m

THEN WE HAVE TO FIND PERIMETER

SO FORMULA IS=2(L+b)

2(20+22)

2*42

84
