Answer:
48.06
Step-by-step explanation:
b^2+c^2=A^2
45+16=42.06
add the extra 6
Answer: 804 meters
Step-by-step explanation:
Area of a circle = πr²
Radius = 16m
π(16)² = 804.2477193 meters
1. You will have to find the height first which could be done by using pythagoras theorem
split the 12 by half giving 6
a^2 = b^2 + c^2
13^2 = 6^2+c^2
169 = 36+c^2
c^2=169-36
c^2=133
c=sqrt133
c= 11.53
area of triangle
1/2 x b x h
1/2 x 6 x 11.53
34.59
34.5(3 sf)
Answer:
First one.
-3 is added to the previous term.
Answer: 
Step-by-step explanation:
Given
Rectangle has an area of 
Suppose rectangle length and width are
and 
If each side is increased by 
Area becomes 
We can write

Substitute the value of width from (ii) in equation (i)

Width corresponding to these lengths

Therfore, we can write the length of the longer side is
