Question

The adjacent sides of a rectangle are in the ratio
7: 4 and its area is 112 cm. Find the length and
breadth of the rectangle.
​

Answer 1

Answer:

breadth =14

length=8

Step-by-step explanation:

let the side be in x

b=7x

l=4x

area =112

area of rectangle=l*b

112=7x*4x

112=28x^2

112\28 = x^2

4=x^2

√4=x

2=x

now,

b=7x

=7*2

=14

and,

l=4x

=4*2

=8
