Question

let us recall the areas of some plane from figures and complete the table ​

Answer 1

Answer:

Step-by-step explanation:

ANSWER:-

1. Square = $a^2$
2. Rectangle= $2(a+b)$
3. Right angle triangle= $\dfrac{1}{2} \times b \times h$
4. Parallelogram = $b \times h$
5. Rhombus = $\dfrac{1}{2} \times ( \sf{d1+d2)}$
6. Circle = $\pi \times r^2$

Things to Note:-

• These all are the areas of the figure with respect to the image given.
• Also,  here are some constants:-
• l is length of the side.
• b is the breadth of the quadrilateral
• d is the diagonal of parallelogram
• r is the radius of the circle.
• Keep a special eye on the units if provided. Make sure to convert them if needed.

Answer 2

Answer:

$\huge \bf \: answer$

1.Name of shape- Triangle

Area - ½ × b × h

2. Name of the shape - Parallelogram

Area - b × h

3. Name of shape - Rhombus

Area- ½ × (D1 + D2)

4. Name of shape - Circle

Area - πr²
