Hey user!
your answer is here..
ATQ,
the length of the base of the triangle is twice it's height.
let the height of the triangle be x.
therefore base of the triangle is 2x.
given area of the triangle = 196km²
==> 1/2 × b × h = 196km²
==> 1/2 × 2x × x = 196km²
==> x × x = 196km²
==> x² = 196km²
==> x = √196
==> x = 14
hence, height of the triangle = x = 14km
base of the triangle = 2x = 2 × 14 = 28km
VERIFICATION :-
area of the triangle = 1/2 × b × h
= 1/2 × 14 × 28
= 7 × 28
= 196km²
hence verified..
cheers!!
Area = 1/2 x base x height
Let the height be x.
Height = x
Base = 2x
Area of triangle = 1/2 x base x heght
Plug base and height into the variables:
(1/2)(2x)(x) = 196
Combine like terms:
x² = 196
Square root both sides:
x = 14
Find Base and height:
Base = x = 14 km
Height = 2x = 2(14) = 28 km
Answer: Height = 28km

Step-by-step explanation:
6 + a
Putting value of a
6 + 3 = 9
5b
Putting value of b
5(2) = 10
C - 1
Putting value of c
12 - 1 = 11
Answer:
-5(1)= -16 + x/3
x/3 - 16 = -5
x/3 = 11
x = 33
