Question

The measure of two adjacent sides of a rectangle are in the ratio 5 : 3. if the perimeter of the rectangle is 80 m, find its length and breadth.​

Answer 1

Answer:let length = 3x

Let breadth = 5x

Perimeter = 2l+2b

80=6x+10x

80 = 16x

x= 5

Length = 15cm

Breadth = 25cm

Step-by-step explanation:

Answer 2

Let length be 5x

breadth be 3x

Perimeter=2(l+b)

80=2(5x+3x)

40=8x

x=5

Length=5×5

=25

Breadth=3×5

=15
