A rectangular sheet of paper is ten 1 by 2 cm long and three three by 4 cm wide.
Find its semiperimeter.
The semiperimeter of the sheet is
cm.
Answers
Answer:
5/4
Step-by-step explanation:
As we can see in the question the two sides of the rectangle are 1/2cm and 3/4 cm and the formula for perimeter of rectangle is 2(l+b) but as we have asked semiperimeter which means perimeter/2 so,
2(l+b)/2 [both 2 cancelled each other]
(1/2+3/4)
(2+3/4) [by taking LCM]
5/4 answer
hope this helps !
Answer:
Answer is fourteen 1 by 4cm
Step-by-step explanation:
GIVEN,
LENGTH= ten 1/2=21/2
BREADTH=three 3/4=15/4
Semi-perimeter of rectangle=2 (L+W) /2
=L+W
=21/2+15/4
=42+15/4
=57/4=Fourteen 1 by 4
