<h2>Question:- Area of the given diagram</h2>
<h2>Answer :- </h2>
Divide the diagram as shown in attachment.
Now first calculate the area of the rectangle having side 1 and 12
So area = length ×breadth
Area = 1× 12 = 12 unit²
Now find the Area of the remaining triangle with sides 12,13,5 units
So
Now put the value as -> base= 5 and height= 12
Now add both areas for your answer
Answer:
x = -2
Step-by-step explanation:
Distribute: 18x + 24 = 4x - 4
Subtract 4x from both sides: 14x + 24 = -4
Subtract 24 from both sides: 14x = -28
Divide both sides by 14: x = -2
