Question

The area of a rectangle is 221 square metre and its length is 4 meter more than Its breadth. What is the measure os its breadth?

Answer 1

Answer:

55.25meter

Step-by-step explanation:

A=l*b

b=?

221=4*b

b=221/4

b=55.25

Answer 2

Step-by-step explanation:

Let the Breadth be X m

Then Length=x+4 m

Given area = 221 sq m

ATP:

l×b = area

so

(x+4) × x = 221

x^2 + 4x = 221

x^2 + 4x -221=0

(x^2+17x)-(13x+221)

x(×+17) - 13(x+17)

(x-13)(x+17)

taking the positive value we get

x-13=0

x=13 (breadth)

and

length= 13+4=17
