2776 . 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

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.

2779 . The area of a rectangle R with width 4 feet is equal to the area of a square S, which has a perimeter of 24 feet. The perimeter of the rectangle R is-

A. 9 ft
B. 16 ft
C. 24 ft
D. 26 ft

Answer: Option D

Explanation:

we know, perimeter of square = 4a atq, 4a = 24 or, a = 6 so, area of square = 6*6 = 36 according to the question, area of rectangle = 36 or, L*W = 36 or, l = 36/4 or, l = 9 perimeter of rectangle = 2*(9 + 4) = 26 ft (ans).

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

Answer: Option D

Explanation:

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

A. 18
B. 12
C. 9
D. 6

View Answer	Favorite Question

Answer: Option B

Explanation:

The length of the other diagonal is x. 
We know, Area  =  1/2 * One diagonal * other diogonal
So, 1/2 *16*x  =  96
x  =  16.

C. The price of a few banned products increased considerably in 2007
D. A decrease in demand for most banned products in 2007 was not the sole cause of the drop in their price

View Answer	Favorite Question

Answer: Option D

Explanation:

Based on the options provided, the assumption that underlies the argument in the passage is:

A decrease in demand for most banned products in 2007 was not the sole cause of the drop in their price.

This assumption suggests that there were other factors besides the decrease in demand that contributed to the drop in the price of banned products in 2007. The argument relies on the idea that the decrease in supply or other factors played a significant role in causing the observed decrease in price, rather than solely relying on the decrease in demand.
