Question

3. Find the perimeter of the following rectangles:
(a) Length = 26 cm; Breadth = 18 cm
(b) Length = 2.4 m; Breadth = 1.6 m
(c) Length = 1.8 m; Breadth = 80 cm
​

Answer 1

Answer:

$\huge\orange{a}\blue{n}\pink{s}{w}\green{e}\red{r} \\ perimeter\: of \: rectangle = 2 \times {l + b}$

a) l=26cm b=18,

p=2x(l+b)

=2x (26+18)

=(2x26)+(2x18)

=52+36

=88ans

b) l=2.4m b=1.6m

p=2x(l+b)

=2x(2.4+1.6)

=(2x2.4)+(2x1.6)

=4.8+3.2

=8.0ans

Hope its help you.
