Answer:
18617.66 ft^2
Step-by-step explanation:
sides of triangular base
a= 145ft ,
b = 257ft ,
c = 290ft
<u>calculate the area of the base </u>
The base is a scalene triangle hence the area is calculated as follows
s = ( a + b + c ) / 2
= ( 145 + 257 + 290 ) / 2 = 346
Area of triangle =
= 18617.66 ft^2
Answer
<h2>4</h2>Step-by-step explanation:
Given,
r = 10
Let's create an equation,
plugging the value of r
Multiply the numbers
Move 5s to L.H.S and change its sign
Similarly, Move 30 to R.H.S and change its sign.
Calculate
The difference sign ( - ) should be cancelled on both sides
Divide both sides of the equation by 5
Calculate
The value of s is 4.
Hope this helps..
