Answer 2

Answer :

1. The area of a square plot is 1600m². The side of the square plot is 40m.

Step-by-step explanation :

To Find,

• The side of square

Solution,

As we know that,

Area of square = side² , therefore

➠ Side² = 1600

➠ Side = √ 1600

➠ Side = 40m

2. The perimeter of a rectangle is 30m its length is 10m and its breadth is 5m.

Step-by-step explanation :

To Find,

• The breadth of rectangle

Solution,

As we know that,

Perimeter of rectangle = 2 ( Length + Breadth ), therefore breadth is,

➠ 2 ( 10 + Breadth ) = 30

➠ 10 + Breadth = 30 / 2

➠ 10 + Breadth = 15

➠ Breadth = 15 - 10

➠ Breadth = 5m.

3. Volume of Cylinder = πr²h.

4. The area of a rectangular field is 250m² is breadth of the field is 10m then the length is 25m.

Step-by-step explanation :

To Find,

• The length of rectangular field.

Solution,

As we know that,

Area of rectangle = Length × Breadth, therefore the length is,

➠ Length × Breadth = Area

➠ Length = Area / Breadth

➠ Length = 250 / 10

➠ Length = 25m.

5. Area of trapezium = 1/2 × ( sum of parallel sides ) × distance between them.
