Question

The perimeter of a square is 48 m. The area of a rectangle is 6 m2 less than the area of this square. If the length
of the rectangle is 23 m, find its breadth.​

Answer 1

Answer:

6m.

Step-by-step explanation:

Side of the square = 48m/4 = 12m.

It's area = 12m × 12m = 144m².

So, the area of the rectangle = 144-6 = 138cm².

i.e., 23m× breadth = 138m²

i.e., breadth = 138m²/23m

Hence, breadth = 6m.

Answer 2

Answer:

breadth = 6.52cm

Step-by-step explanation:

Let side of square be A

4a = 48

a = 12

area of square = a^2 = 12*12 = 144cm^2

area of rectangle = 23 * b

144 = (23*b)-6

150 = 23 * b

b = 150/23= 6.52cm

breadth = 6.52cm
