2956 . The area of a rectangle is 200 sq. meter. If the length is twice the breadth, what is the perimeter of the rectangle?

A. 60
B. 30
C. 40
D. 50

View Answer	Favorite Question	Report

Answer: Option A

Explanation:

Let L be the length and B be the breadth.

So, L x B = 200

or, 2B x B = 200

or, B2 = 100

or, B = 10

So, L = 2B = 2 x 10 = 20

Therefore, the perimeter of the rectangle = 2 (L + B) = 2 (20 + 10) = 2 x 30 = 60.

B. 160 m
C. 160 cm
D. 1.6 cm

Answer: Option B

Explanation:

The scale of the map is 1 cm to 100 m. This means that 1 cm on the map represents 100 meters in reality.

Given that the length on the map is 3.25 cm, you can find the actual length by multiplying it by the scale factor:

Actual length = Length on map × Scale factor = 3.25 cm × 100 m/cm = 325 m

Now, you mentioned that the area of the rectangular field is 52000 square meters. The area of a rectangle is given by the formula:

Area=Length×Breadth

We know the area is 52000 square meters and the length is 325 meters. Substituting these values into the formula, we can find the breadth:

52000m2=325m×Breadth

Breadth=325m52000m2

Breadth=160m

Side of the square = 24/4 = 6.

Area of the square = 62 = 36

ATQ, Area of rectangle, Length x width = 36

or, Length x 4 = 36

or, Length = 9

So, the perimeter of the rectangle = 2(Length + width) = 2(9 + 4) = 26
