Question

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

Answer 1

Answer:

Mark me brinlyiest

Step-by-step explanation:

Let x be the common multiple.

Length = 4x

Breadth = 3x

According to Pythagoras theorem,

(4x)²+(3x)²=(25)²

16x²+9x²=625

25x²=625

x²=625/25

X =5

So,

Length = 4x = 20 cm

Breadth = 3x = 15 cm

Perimeter = 2(l×b)

= 2 (20 + 15)

= 70 cm

So, perimeter of rectangle is 70 cm.
