Answer:
Diagonal=11.3m
Area of square (A) =1/2*d^2
=1/2*(11.3)^2
=63.845m^2
We know,
Area of square A= l^2
63.845=l^2
L=

L=7.99m
Now,
Perimeter of square =4l
=4*7.99
=31.96m
Answer:
Step-by-step explanation:
for right-angled triangle: a^2 + b^2 = c^2
given a = 5 n b = 10
c^2 = 5^2 + 10^2
= 25 + 100
= 125
c = sqrt(125)
= 5*sqrt(5)
