Question

is Any genius here who can answer above both question correctly
​

Answer 1

EXPLANATION

(1) Length of rectangular park = 30 m

Breadth of rectangular park = 20 m

We know that, Perimeter of rectangle =

2 ( L + B) , So ,

= 2( 20 + 30) m

= 2 × 50

= 100 m

So, the perimeter of the rectangular Park is = 100 m

Now,

Cost of fencing park = rs. 15 per sq. m

= rs. (100 × 15) = rs. 1500

So, the total cost of fencing the rectangular park = rs. 1500

(2) Perimeter of rectangle = 100 cm

Perimeter of square = 100 cm

We know, Perimeter of square

= 4 × side , Then

= 4 × side = 100 cm

= side = (100 ÷ 4) cm

= side = 25 cm

So, side of square = 25 cm

Now, according to question the breadth of the

rectangle is 2 cm less than side of square.

So, the breadth of the rectangle is

= (25 - 2) cm = 23 cm

Now, Perimeter of rectangle = 2(L + B)

= 2 ( L + 23) = 100

= 2L + 46 = 100

= 2L = 100 - 46

= 2L = 54

= L = 54 ÷ 2

= L = 27 cm

Hence, Breadth of rectangle = 23 cm

Length of rectangle = 27 cm

Sorry friend, I am not a genius but I always try to help everyone.

(Hope it will help u)

Answer 2

Answer:

hi

(1) Length of rectangular park = 30 m

Breadth of rectangular park = 20 m

We know that, Perimeter of rectangle =

2 ( L + B) , So ,

= 2( 20 + 30) m

= 2 × 50

= 100 m

So, the perimeter of the rectangular Park is = 100 m

Now,

Cost of fencing park = rs. 15 per sq. m

= rs. (100 × 15) = rs. 1500

So, the total cost of fencing the rectangular park = rs. 1500

(2) Perimeter of rectangle = 100 cm

Perimeter of square = 100 cm

We know, Perimeter of square

= 4 × side , Then

= 4 × side = 100 cm

= side = (100 ÷ 4) cm

= side = 25 cm

So, side of square = 25 cm

Now, according to question the breadth of the

rectangle is 2 cm less than side of square.

So, the breadth of the rectangle is

= (25 - 2) cm = 23 cm

Now, Perimeter of rectangle = 2(L + B)

= 2 ( L + 23) = 100

= 2L + 46 = 100

= 2L = 100 - 46

= 2L = 54

= L = 54 ÷ 2

= L = 27 cm

Hence, Breadth of rectangle = 23 cm

Length of rectangle = 27 cm
