Question

find the ratios of the perimeter of the shaded portion to the perimeter of the whole figure​

Answer 1

Answer:

7 : 15

Step-by-step explanation:

the perimeter of the shaded portion is ;

p = 2 ( l + b )

= 2 ( 4 + 3 )

= 2 × 7

= 14

the perimeter of the whole figure ;

= 2 ( 7 + 8 )

= 2 × 15

= 30

the ratio of the perimeter of the shaded part and the perimeter whole figure is ;

= 14 : 30

= 7 : 15
