The diagonals of rectangle are measure 25 cm each . If the length and breadth of the rectangle are in the ratio 3:4, find the area of the rectangle.

Answer» ONG>Answer:

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.
