Answer:
Summary Many simple inequalities can be solved by adding, subtracting, multiplying or dividing both sides until you are left with the variable on its own. But these things will change direction of the inequality: Multiplying or dividing both sides by a negative number. Swapping left and right hand sides
Step-by-step explanation:
The area of a rectangular shape is found my multiplying the base x height. Since squares have the same measure all the way around the base must be equal to height so b x h for a square is equal to (b x b)=b^2 or (h x h)^2 they are the same to using b for base we have b^2=196 so sqrt(196) = each side is 14sqft. To find the perimeter we just add all the sides to get (14+14+14+14) or (14*4)= 56sqft.
Answer:
16%
Step-by-step explanation:
Let
x----------> length of the base
y----------> height
we know that
[the area of triangle]=[length of the base]*[height]/2
x=2y
A=225 km²
225=x*y/2---------> 225=(2y)*y/2-----> y²=225--------> y=15 km
x=2y--------> x=2*15------> x=30 km
the answer is
the height is 15 km
