friends please answer it then I mark as brainlist
Answers
Answer:
1)47.61cm^2
Explanation:
ATQ,
let the side of square be x
Perimeter of square=4×Side
therefore,
4x=27.6cm
x=27.6/4=6.9
therefore,
Area of Square is =Side ×Side
6.9×6.9=47.61cm^2
I hope you have Understood the first part...If you understood pls mark me as a brainlist...
Thank you.
2)Answer)35.76cm^2
ATQ,
perimeter of the rectangle =2(l+b)
l=7.45
therefore,
2(7.45+b)=24.5
14.9+2b=24.5
2b=24.5-14.9
2b=9.6
b=9.6/2
b=4.8
area of rectangle=Length×Breath
therefore=7.45×4.8=35.76cm^2
I hope you have Understood the second part also...If you understood pls mark me as a brainlist...
Thank you.
Answer:
1)
2) P = 2(l×b)
24.5 = 2(7.45+b)
24.5/2 = 7.45+b
12.25-7.45 = b
b = 4.8cm
area = lb
= 7.45×4.8
= 35.76cm^2
3) Are of rectangle = l×b
= 5×2
= 10
Perimeter of rectangle = 2(l+b)
= 2(5+2)
= 2×7
= 14
= 14×10/3.6
= 140/36
= 3.888
= 4
4)
5) Diagonal of square with side a = a(root2)
Side of square = a = ?
a(root2) = 5(root2)
a = 5cm
area of square = a2
= (5) square
= 25
area of square = 25 sq cm
6) We known that area of square = (diagonal)^2/2
(diagonal) ^2/2 = 100
(diagonal)^2= 200
(diagonal) = √200
= 14.14cm
7) Length of rectangle = 12cm
Length of each of its diagonal = 15cm
• diagonal = √(length)^2 (breadth)^2
• 15 = √(12)^2 + (breadth)^2
squaring both the sides we get
• 15^2 = 12^2 breadth^2
• 225-144 = breadth^2
• breadth^2 = 81
• breadth = √81
• breadth = 9cm
