Answer:
11.7 cm
Step-by-step explanation:
Using Pythagoras Theorem
AC² = AB² + BC²
AB = 4 cm
BC = 11 cm
AC² = 4² + 11²
AC = √4² + 11²
AC =✓137
AC = 11.704699911 cm
Approximately = 11.7 cm
Length AC = 11.7cm
Answer:
x = 129
Step-by-step explanation:
x = 129 because of alternate interior angles
Answer:
Length, l = 10 m, breadth = 8 m
Step-by-step explanation:
Let l be the length and b be the width of the rectangle.
The area of a rectangle is given by :
A = lb
80 = lb ...(1)
The perimeter of a rectangle is given by :
P = 2(l+b)
36 = 2(l+b)
18 = (l+b) ....(2)
We need to solve equation (1) and (2). On solving we get :
l = 10, b = 8
So, the dimensions of the shop is 10 m and 8 m.
