Question

7. Find the perimeter of a rectangle whose:
(a) length = 24 cm, breadth = 17 cm
(b) length = 42 m, breadth = 20 m
(c) length = 36 m, breadth = 15 m



​

Answer 1

Answer:

We know,

Perimeter of a rectangle = 2( l + b), where l = length of rectangle

                                                                      b = breadth of rectangle

(a) Here, l = 24 cm and b = 17 cm

Perimeter = 2(24 + 17)

Perimeter = 2(41)

Perimeter = 82 cm

(b) Here, l = 42 m and b = 20 m

Perimeter = 2(42 + 20)

Perimeter = 2(62)

Perimeter = 124 m

(c) Here, l= 36 m and b = 15 m

Perimeter = 2(36 + 15)

Perimeter = 2(51)

Perimeter = 102 m
