8 0

Answer:

8

Step-by-step explanation:

Considering the given value of sum of interior angles with exclusion of one to be 1070 then we can write it as

1070=180(n-2) where n is the number of sides required here.

Making n the subject of the formula then following step by step

n-2=\frac {1070}{180}

n=\frac {1070}{180}+2\\n=7.9444444444444\approx 8

Therefore, the shape is octagon and it has 8 sides.

A rectangular sheet of paper is 12 1/2 cm long and 10 2/3 cm wide.Find it's perimeter​
ra1l [238]

Answer:

Given

length of rectangular sheet of paper is 12 (1/2) i.e. (25/2)

Breadth of rectangular sheet of paper is 10 (2/3) i.e. (32/3)

But we know that perimeter of rectangle = 2 (length + breadth)

Perimeter of rectangular sheet = 2 [(25/2) + (32/3)]

LCM of 2 and 3 is 6,

by taking this and simplifying we get

Perimeter = 2[(25 × 3)/6 + (32 × 2)/6]

= 2[(75/6) + (64/6)]

= 2(139/6) = (139/3)

= 46 (1/3) cm
