Hi love...
The correct answer after solving for d is D=78. That’s a quick answer, but I can give you steps on how to solve.
1. Simplify both sides of the equation
2. Isolate the variable
3. Simplify
Then you’d have the answer!
Please let me know if you need further assistance! Have a jolly evening.

I’m using the same thing
Answer: perimeter = 96mm, Area = 564mm².
Step-by-step explanation:
From the diagram, it is a trapezium, it has a rectangle joined together by a right angled triangle. Now to find the perimeter, we add all the dimensions together. To get the other side of the rectangle, which is also the perpendicular height of the figure, we take the Pythagoras. Let the perpendicular height = x
Therefore,
25² = ײ + 7²
625 = x² + 49
x² = 625 - 49
x² = 576
x. = √576
= 24.
Now the perimeter
= 20 + 25 + 7 + 20 + 24
= 96mm.
Area of the figure will be
= 1/2( a + b )h
Where a = 20, b = 20 + 7 = 27 and h = 24, now substitute for the values
( 20 + 27) x 24
---------------------
2
= 47 x 24/2
= 47 x 12
= 564mm²
1/4 , 1/2 , 2/3 , 5/6
