Question

EXERCISE 10.1
1.) Find the perimeter of the rectangle in which
(a) Length = 14.8 m, Breadth=5.5 m
Length = 16 m 50 cm, Breadthc = 11​

Answer 1

Answer:

perimeter of triangle is = l*b

= 14.8*5.5

=81.4m^2

perimeter of triangle is = l*b

= 16*11

= 176m^2

Answer 2

Answer:

A) 40.6m

B) 33m or 3300cm

Step-by-step explanation:

Answer. (a) = perimeter of the rectangle = 2(length+breadth)

Given,

length = 14.8m

breadth =5.5m

perimeter =2(l+b)

2(14.8+5.5)

2(20.3)

perimeter =40.6m. (answer )

B) given,

length = 16m or 1600cm

breadth = 50cm

perimeter = 2(l+b)

2(1600+50)

2(1650)

perimeter = 3300cm or 33m. answer
