Answer:
a) As sides of squares are always equal.
So,
BC=CD
2b+CF=a+b
CF= a+b-2b
CF= a-b
b) Area of rectangle CDEF= CDxCF
=(a+b)(a-b)
=(a²-b²)
Hope it helps :-)
The value of x when the triangle and the parallelogram have the same area is 6 units
<h3>The dimensions</h3>
The dimension of the parallelogram is given as:
The dimension of the triangle is given as:
<h3>Areas</h3>
The area of a shape is the amount of space it occupies
The area of the parallelogram is calculated as:

The area of the triangle is calculated as:


Both areas are equal.
So, we have:

Divide both sides by x

Subtract 4 from both sides

Hence, the value of x is 6 units
