Question

Please tell me the correct ansewer ​

Answer 1

1st question -

Given :-

Perimeter of square is 36 metre.

To Find :-

Side of square .

Solution :-

$\boxed{\sf{\red{\implies \: Perimeter = 4 \times Side }}}$

→ 36 = 4 × side

→ Side = 36/4

→ Side = 9 meter

2nd question :-

Given :-

Sides of triangle are 6 and 4 cm and 8 cm .

To Find :-

Perimeter of triangle.

Solution :-

$\boxed{\sf{\red{\implies \: Perimeter = Sum\ of\ sides }}}$

→ Perimeter = 4+6+8

→ Perimeter = 18 cm

3rd question :-

Given :-

Sides of rectangle are 6cm and 8cm.

To Find :-

Perimeter of rectangle.

Solution :-

$\boxed{\sf{\red{\implies \: Perimeter = 2\times (l+b) }}}$

→ Perimeter = 2( 6+8)

→ Perimeter = 2( 14)

→ Perimeter = 28 cm

Answer 2

Answer:

1) Answer is 5 (2) Answer 18cm (3)Answer 34cm

Explanation:

1) because perimiter of square is = 4 × side

so 20 = 4× side ( finding length of side 4will come left side side then we will divide it

20 =4× side

20/4

= 5

(2) perimeter of triangle is = a+b+c

So , 6cm +4cm + 8cm

= 18 cm

(3). perimeter of rectangle = 2 ( l + b)

So, the sides are its lenght and breadth (width)

= 2 ( 8+6)

2× 14

= 34 cm
