The length and breadth of a rectangle are in the ratio 4 : 3. If the diagonal measures 25 cm then the perimeter of the rectangle is

Question

Philoid · Accepted Answer

Let x be the common multiple.

Length = 4x

Breadth = 3x

According to Pythagoras theorem,

X =5

So,

Length = 4x = 20 cm

Breadth = 3x = 15 cm

Perimeter =

= 2 (20 + 15)

= 70 cm

So, perimeter of rectangle is 70 cm.
