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

A: 42 m

B: 84 m

C: 48 m

D: 24 m

Correct Answer : B

Given: Area of rectangular plot = 440 m2.

Length = 22 m.

To find: Breadth and perimeter of the rectangular plot.

As we know,

Area = Length × Breadth

Now, substitute the values in the formula to find the breadth.

440 = 22 × Breadth

Hence, Breadth = 440/22 = 20 m

Therefore, the breadth of the rectangular plot = 20 m.

Now, substitute the length and breadth values in the perimeter formula,

Perimeter = 2 (Length + Breadth) units

Perimeter = 2 (22 + 20)

Perimeter = 2 (42)

Perimeter = 84 m

Therefore, the perimeter of the rectangular plot of land is 84 m.
