Question

The area of a rectangular field is 1470 m². Find the breadth of the field, if length of the field is 42 m. The area of a square is 144 m². Find the side of the square.​

Answer 1

Step-by-step explanation:

Length of the rectangular field=42m

Area of a rectangular field=1470 m²

Let breadth of the rectangular field be b

Area=Length × Breadth

1470=42×b

b=1470/42=35m

Area of a square =144m²

Side of a square =sqrt(area)=sqrt(144)=12m

Answer 2

Given:

Area of rectangle = 1470 $m^{2}$

Length of rectangle = 42 m

Area of square = 144 $m^{2}$

To Find:

(1) Breadth of field

(2) Side of square

Calculation:

Area of rectangle is given as = length of rectangle * breadth of rectangle

• Area of rectangle = l * b
• 1470 = 42 * b
• Breadth of rectangle = 35 m

Area of square is given as = length of side * length of side

• Area of square = $a^{2}$
• 144 = $a^{2}$
• a = 12 m

Answer:

Breadth of rectangle is 35 metre.

Side of square is 12 metre.
