Question

LIV. Q9. The sides of a rectangle are in the ratio 2: 3 and its perimeter is 20 cm. Draw the rectangle.​

Answer 1

Step-by-step explanation:

let the ratios be 2x and 3x

perimeter=20cm

length = 2x

Breadth = 3x

p = 2×(l+b)

20 =2(2x+3x)

20 = 2×5x

20 =10x

x = 20/10

x = 2

length = 2×2=4cm

breadth=2×3=6cm
