Question

In the given figure find

1. Perimeter of Rectangle
2.Perimeter of Triangle ​

Answer 1

Answer:

1. 314/10 = 31.4 cm

2. 37/4 = 9.25 cm

Step-by-step explanation:

1. BE = CD = 3 1/2 = 7/2

ED = BC = 5 1/5 = 26/5

PERIMETER = (7/2+26/5) × 2

= [(35+52)/10] × 2

= (157/10) × 2

= 15.7 × 2

= 31.4cm.

2. AB = 2 1/2 = 5/2

BE = 3 1/2 = 7/2

AE = 3 1/4 = 13/4

PERIMETER = AB+BE+AE

= 5/2+7/2+13/4

= (10+7+13)/4

= 37/4

= 9.25cm.
