Question

The area of a rectangular lawn is 150 sq.m. If its length is 10 m, find its perimeter

Answer 1

Answer:

The answer is 50

Step-by-step explanation:

Area=length×breadth

150²m=10× x(assuming breadth=x)

x=150/10

x=15

Checking it 10×15=150

Perimeter=2(length+breadth)

2(15+10)

2×25

50

Answer 2

Answer:

✩ Answer ✓

Here, total number of hours = 24

So,

The central angle = (component value/24) × 360°

Now, the pie-chart can be constructed by using the given data.

Steps to construct:

Step 1: Draw the circle of an appropriate radius.

Step 2: Draw a vertical radius anywhere inside the circle.

Step 3: Choose the largest central angle. Here, it is 120o. Construct a sector of central angle 120o whose one radius coincides with the radius drawn in step 2 and the other radius is in clockwise direction to the vertical radius.

Step 4: Construct other sectors representing other values in clockwise direction in descending order of magnitudes of their central angles.

Step 5: Shade the sectors so obtained by different colours and label them as shown in below figure.
