Question

73. The
area of
length of rectangle is 1936 sq cm. if the length of rectangle is 4 times its breadth, fInd the dimension of the rectangle​

Answer 1

Answer: let breadth be b.

Length(l)=4b------(1)

Now, area of rectangle is l×b.---------(2).

Substitute (1) in (2) ,

4b×b=Area

4b^2=1936.

b^2=1936÷4

b^2=484

b=√484

b=22cm.

Therefore, l=4b

l=88cm.

Hope it helps :D

Answer 2

Answer:

Length =88Cm and Breadth=22Cm

Step-by-step explanation:

Let breadth =x cm

Then length =4x cm

According to the problem

4x.x=1936

Or, 4x^2=1936

Or, x^2=1936/4

Or, x^2=484

Or,x^2=22^2

Or, x=22

Then Length will be =22x4=88

Then the breadth will be =22
