Answer:
B) 42
Step-by-step explanation:
Area = b h
Area = x 12 x7
Area = 42
Let x be the <span>heights of a maple tree and y be the height of the cherry tree.
We know:
</span>
<span>The new ratio is obtained like this:
</span>
.
From the above equation we get
.
then
Solving the above equation for y we get:
So
So the first tree is (400-160=240) more taller than cherry tree.
Area of square is a^2
4^2 = 16
the area is 16 units
