The area of the circle is 2464 cm2 and the ratio of the breadth of the rectangle to radius of the circle is 6:7. If the circumference of the circle is equal to the perimeter of the rectangle, then what is the area of the rectangle.
Detailed Solution for Test: Mensuration- 2 - Question 4

Area of the circle=πr2

2464 = 22/7 * r2

Radius of the circle=28 cm

Circumference of the circle=2 * π* r =2 * 22/7 * 28 

= 176 cm

Breadth of the rectangle=6/7 * 28=24 cm

Perimeter of the rectangle=2 * (l + b)

176 = 2 * (l + 24)

Length of the rectangle = 64 cm

Area of the rectangle = l * b = 24 * 64 = 1536 cm2

The area of a rhombus is 200 cm², and one of its diagonals is 20 cm. The length of the other diagonal is _____
Detailed Solution for Test: Mensuration- 2 - Question 10

Let the length of one diagonal be d1 = 20 cm, and the length of the other diagonal be d2

The formula for the area of a rhombus is:
Area = 1/2 x d1 x d2

Substitute the given values:

200 cm² = 1/2 x 20 x d2

200 cm² = 10 x d2

20cm = d2
