Question

The adjacent sides of rectangle are in the ratio 7:4 its area is 112cm find length breadth

Answer 1

Answer:

length=14cm breadth=8cm

Answer 2

let the length be 7x and breadth be 4y so according to question :-

AREA = 7x × 4x

112 = 28x^2

$\frac{112}{28}$

= x^2

4 = x^2

2 = x

now length = 2 × 7 = 14

and breadth = 4 × 2 = 8
