Question

The breadth of a rectangular plot of land, if its area is 440sq.m and length is
22cm, then its
perimeter is
a) 72cm
b) 84cm
c) 96cm
d) none of the

Answer 1

Answer:

Step-by-step explanation:

This is your answer....

Given :- area of rectangular plot = 440 m².

length of plot = 22 m.  

We know that area of rectangle = l × b

so,

440 = 22 × b

b = 440/22

b = 20 m.

Hence the breadth of the plot is 20 m.

now moving to perimeter....  

As we know that perimeter of rectangle= 2(l+b)

So,

2 ( 22+20)

= 2 × 42

= 84 m.

Hence the perimeter of the rectangular plot is 84 m.

Hope you got the answer...

Answer 2

Answer:

• (b) 84 cm .

Given :- The area of rectangular plot of land is 440 cm² and length is 22 cm .

To Find :- Breadth and perimeter of rectangular plot of land ?

Formula used :-

• Area of rectangle = Length × Breadth
• Perimeter of rectangle = 2(Length + Breadth)

Solution :-

→ Area of rectangular plot of land = 440 cm²

→ Length × Breadth = 440 cm²

→ 22 × Breadth = 440

→ 22 × Breadth = 22 × 20

dividing both sides by 22,

→ Breadth = 20 cm

now,

→ Perimeter of rectangular plot of land = 2(Length + Breadth)

→ Required perimeter = 2(22 + 20)

→ Required perimeter = 2 × 42

→ Required perimeter = 84 cm (Ans.)

Hence, the breadth of the rectangular plot of land is equal to 20 cm and its perimeter is equal to (b) 84 cm .
