Answer:
43cm²
Step-by-step explanation:
let's first consider the area of a square.
the area is L² which means all sides are equal so we take the length times the breadth which is both equal because like we said all sides are equal.
so to find the side of the square using the area, we take the square root of both of the area.

and also

so we have the height of the triangle as 5cm and the base is 4.2cm.
now, from the triangle, since we have two sides and it's a right-angled, we can use Pythagoras' formula.

so the side 6.53cm is also the same side as the largest triangle. Since it's a square, all sides are equal. So we find the area of the largest triangle by using the formula
Area = L²
Area = 6.53²
Area = 42.6cm
the nearest cm square
Area = 43cm²
The fraction is written as 3/4.
If you divide 3 by 4 you will get the decimal.
Answer:
Line DG is equal to 16
Step-by-step explanation:
We know that
In a parallelogram, opposite sides are congruent.
Line DG is congruent to line FE, so they must have sides of equal length.
4z-48=z
4z=z+48
3z=48
48/3=z
16=z
Now we know that the variable is 16 increments, so we sub the 16 in for z in line DG
4(16)-48
64-48=16
Line DG is equal to 16
If you can multiply or divide the original triangle to equal the second triangle, and if the angles are the same, then it is a dilation
